Q&A 5

This is a LooseRounds.com Q&A session.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

1.  Is it better to leave a few rounds out of magazines to save the spring?

Shawn- It is perfectly harmless to load  magazine to its full capacity. Springs wear form cycling , not from being under tension. Most of the time the problem in feeding is from faulty feed lips and not the spring.

Howard-  That started with the USGI 20 round mags which could have their spring installed backwards and would still function with 18 rounds, but would jam with 20.  Nowdays I would not buy or use mags that were not 100% reliable when loaded to capacity.

2.  What slings do  you recommend?

Howard-  First I would suggest reading Vickers article on slings.  It can be found here.  Shawn and I recommend for the AR15 slings like the Vickers sling, Viking Tactics sling, and similar 2 points.

3. How do you tighten the screws on a pre 64 Model 70 Winchester?

You tighten the front and rear screws the same as you would any other wood-stocked bolt action. but, the middle screw that holds the floor plate on is just barely tightened finger tight, just enough to let the floor plate close. if you tighten it much more it causes problems for the rifle.

4.  how do you use a weapon flash light

Howard-  Tactics and placement of a weapon light could be an article in it self.  However first a safety and employment.  I was working on a write up about it, however I found that Mas Ayoob beat me to it and did a better job.  I highly recommend looking at his article on the use of weapon lights that can be found here.

5. What is the best aimpoint for general use?

Howard- The answer depends on if you are running the aimpoint co-witness with iron sights, or without iron sights in the view of the window. If you are not co-witness with iron sights, I would highly recommend the Aimpoint T1 or H1 for its compact size and light weight. However if you are co-witnessessing with iron sights, a larger window is usually preferred. If you have the money, I would recommend the Aimpoint Comp M4, however the Aimpoint PRO offers similar excellent features at an economical price. The Aimpoint PRO is probably the best value for the person with a limited budget.

1.  colt le901-16s release date?

Howard:  The Colt 901 has already been released and can be purchased.  However currently supplies are limited.

2.  what finish does the colt rail gun have 

Shawn:  Stainless steel or Stainless with a black ceracoat coating.

3.  winchester model 70 pre 64 iron sights?

Shawn:  The target or National Match version came with Lyman or Redfield Olympic iron sights.  Sporters came with a simple leaf sight.

4.  Just out of curiosity, what’s the average accuracy you’re getting out of ‘regular’ .308 ball ammo out of the Colt?  I saw the one line in your write up about German DAG (approx 2.5 inch groups).  Is that about what you average with M80/Portuguese/S. African?

Shawn:  NMH ball also gave about 2.5 MOA.  150 grain soft point hunting ammo from Federal gave about a 1.5 inch group at 100 yards.

Howard:  Surplus can vary greatly, don’t expect match results with surplus, often 2-5 MOA is to be expected with good surplus.  Stuff like Wolf will perform worse.

5.  What is the coolest MOLLE vest?

Shawn:  What do you mean, to wear to the gun prom, or what is the least hot.  The coolest (temperature) is probably the SDS MOLLE 2 Fighting Load Carrier (FLC) as issued by the military.  Coolest for showing off would maybe be the Eagle Maritime CIRAS or the Marine Corps Scaleable Plate Carrier.

Howard:  The FLC is good, but maybe not the coolest in temperature.  Something like a basic chest carrier with H harnes like backing might be coolest.  As for cool factor, perhaps the CRYE Jumpable Plate Carrier (JPC).  *For coolest just look Titleist1, an active poster on AR15.com.

6.  How do you make homemade body armor

Shawn:  Under no circumstances depend on homemade body armor to save your life.  There is no way you can replicate the quality of a properly manufacturer plates of soft armor.

7.  is the fn pbr 24inch fluted barrel a heavy barrel

Shawn:  I could call it a medium heavy, it tapers down.

8.  Do Glocks shoot loose with age?

Howard:  Yes, all things wear.  Glock triggers will generally get smoother.  Some people claim that replacing the Slide Lock in a old Glock that is shooting poorly will tighten up barrel lockup and improve grouping.  Some parts like the plastic tubular insert in the striker channel can erode and come loose from wear.

9.  do you have to break in a gun with national match barrel

Shawn:  Well its a little complicated, but to start off it is important to note that a quality national match barrel will come polished and hand lapped from the maker.  So you should not have to break one in.

LooseRounds over years have found that breaking in barrels is a waste of time, regardless if its custom match or factory.  Usually you will do more cleaning rod damage to the barrel then any amount of improvement you could have helped.

1.  Sirs,

A friend and I are working up loads for his hunting rifle and during the discussions a question came up that neither of us have seen addressed. When shooting (right-handed) for group from a bench, with the rifle supported by sandbags at the forearm and butstock, what is the best position for the left hand on the rifle?

Is it important to control the forearm laterally with a hand on the forearm? I recently watched a video showing a rifle with a bipod and butstock monopod being fired with the left hand on the monopod controlling vertical sight movement. The bipod controls the lateral movement but maybe not so much during recoil.

We’d like to read your opinions (and reasons) on this question.

Thanks. We enjoy your site.

Howard:  Normally the forend/handguards are on a rest/sandbags/bipod, and the left hand is used to adjust the rear bag/monopod for elevation.

Sometimes for expediences the left hand is put directly under the stock(often as a fist) and clenched or unclenched to hold up the butt of the rifle.
Just resting the front of the rifle on a rest helps steady the rifle a great deal, but when the rear of the rifle is resting on something as well, the rifle is far more stable.  When using something like a competition bench rest all adjustments are done from the front rest.  However for most of us, the front rest we use(bipod, sandbag, wooden block, backpack, enemy cadaver, etc) is not so adjustable.  So we pivot the rifle on the front rest for left and right, and we lift or drop the buttstock for up and down.  Using a rear rest gives that additional stability, and the left hand(for a right handed shooter) is used to control/adjust that rear rest.
2.  I am trying to help new hunters as well as others to select and purchase the right optics for the type of gun as well as the type of hunting or shooting they enjoy doing. The right equipment is a sure way to be a safe and happy hunter.
Shawn:  For medium to large size game:  For deep woods or anything other then open plains something like a 1-5x.  If you are in an area like out west where you have longer distances, something like a 3.5-10x.  Preference for 10x or under so you don’t have to worry about adjusting parallax because you don’t have time to fiddle with it in the field.  No bigger then a 40mm objective lens as long as the optic is clear, because anything much bigger doesn’t really make anything much bright.  Larger just adds weight and size that makes the rifle top heavy.  Stay away from scopes with friction plate elevation or windage adjustments, you want to be able to zero as precisely as you can.  For varmint hunting, I prefer 12-20 magnification scopes with target turrets with positive clicks with a click value of no less then 1/4 MOA.  Has to be adjustable for focusing and objective lens size doesn’t really matter, go as large as you like.  For long range varminting, scope base and ring selection is just as important as the scope.
Howard:  The problem with picking a scope is that there are so many options and personal preferences.  Thicker reticles can be faster to pick up, but may cover a target at longer ranges.  Too much magnification can make it slower to acquire targets.  Adjustments values need to be appropriate for the type of precision necessary for the type of shooting.  I think a decent 3-9 would cover the average deer or hog hunters needs.
Optics are very much a personal preference.  LooseRounds.com always recommends that you always try to buy the highest quality optics you can afford.
3.  does the colt rail gun have a throated barrel?
Shawn:  Yes and a polished feed ramp.
4.  How did the Unertl scope hold up in tropical climate?
Shawn:  The Unertl in the war in Vietnam did tend to fog up at time in the rainy season.  But this isn’t the flaw that it seems to be, John Unertl designed the scope to be very easy to repair and worked on by the end user.  So the Unertl is easily taken apart and can be dried off or wiped dry and cleaned with simple tools.  Even the cross hair was designed to be replaceable by the end user with anything suitable in the event of failure.  With those in mind, you could seal the scope yourself, at the cost of no longer being able to do field expedient disassemble.  Other then that, the Unertl scope was very difficult to break or render unusable.
5.  can i own a krinkov if it has no stock
Howard:  You can own an AK pistol.  For example the Draco and the SLR106-47.  However I do not recommend this setup as they are heavy and awkward.  Shooting them with out a sling for stabilization is also awkward, best used for turning money(ammo) into noise.
6.  Is the Colt 901 an AR10
Howard:  No.  While the 901 is a 308 AR like the AR10s of old.  However now the term AR10 refers specifically to the trademarked Armalite (Eagle) brand .308 rifles.  The Armalites mostly use a M14 style mag.  Often you will see people refer to the lesser DPMS (Panther) .308s as AR10s.  These are not AR10s but a whole different model.  No one with a premium .308 such as a LaRue OBR, Colt 901, KAC EMC or SR25, GAP, LWRC REPR, POF, etc call their .308 variant an AR10.  Only people who have purchased the cheaper DPMS tend to want to call it by a most expensive models trademark.
7.  What ammo does the USMC scout snipers use?
Shawn:  Ammo used in all USMC sniper system is the M118LR.  175 grain Serria hollow point boat tail bullet and Lake City match brass.  Of course, other loads like ball or tracer can be used in specialty or emergencies situations.
8.  Will the Magpul BAD lever work on the Sig 716?
Howard:  No.
9.  Surefire 60 round magazine stripper clip?
Shawn:  The Surefire mags will accept stripper clips when loaded with a stripper clip guide.
Howard:  The Stripper clip guide is often called a “spoon”.

Q&A 2

This is the second session of LooseRounds.com Q&A.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

Shawn and I thank Catherine Kim for the article she submitted and to thank Duncan Larsen for the articles he has submitted and for his help on our Facebook page.  We also appreciate the work CJ does as an editor on LooseRounds.com, he keeps us from looking as illiterate as we are.  Thanks also to Adam O’quinn for taking the 901 in action shots.

 

1.  How are the Surefire 60 round mags?

Howard:  Both Shawn and I own Surefire 60 round mags and we like them very much.  While we haven’t torture tested them, or run them very heavily, they appear to be good mags.  We recommend them, but be sure to test each mag before you rely on them.

2.  ar15 bolt face ring

Howard: Well that is not much of a question.  Normal wear on the bolt face may leave little pits, and a ring corresponding to the primer on the round.  If any pits extend into the firing pin channel, replace the bolt.

ARMY TM 9-1005-319-23&P and AIR FORCE TO 11W3-5-5-42 page 3-22 explain:

(a) Bolt faces with a cluster of pits which are touching or tightly grouped, covering an area measuring approximately 1,8 Inch across, will be rejected and replaced.

(b) Bolts which contain individual pits or a scattered pattern will not be cause for rejection.

(c) Bolts that contain pits extending Into the firing pin hole will not be rejected unless firing pin hole gaging check determines excess wear.

(d) Rings on the bolt face (machine tool marks), grooves, or ridges less than approximately 0.010 inch will not be cause for rejection.

3.  Winchester Model 70 used in Vietnam?

Shawn:  There were two types, one was the heavy barrel national match that had a target stock and a heavy barrel with a sporter stock.  The sporter stock model started off as sporters and then the Rifle Team Equipment (RTE) armorers added match heavy barrels.  Both were glass bedded and free floated by the RTE armors.

4.  Duty holster for 1911 with light

Shawn:  LooseRounds uses a Dark Star Gear holster kydex that can be used for IWB or outside carry.  Found it to be best of its type tested so far.

5.  scar 17 vs sig 716

Howard:  Right now you can get more parts and accessories for the Sig, such as cheap quality Magpul mags.  However as for company quality control and function out of the box, I would trust FN more then Sig.

6.  What cheap asian are good?

Howard:  Well, the following are optics and accessories are junk.  UTG, NcStar, Leapers, Counter Sniper.  Some of Tapco stuff is good, but much of it is junk.  ATI is similar with mixed quality items and plenty of junk.

Q&A Session 1

This is the first session of LooseRounds.com Q&A.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

1. Aimpoint vs. Eotech?

Howard:  Shawn and I advocate the Aimpoint.  While early Eotechs were a far superior optic to early Aimpoint, modern Aimpoints easily beat Eotechs.  Aimpoints like the PRO, T-1, and Comp M4 have superior battery life over the Eotechs.  An Aimpoint will run for years while an Eotech will run for a month on a single battery.  In a recent drop test by Andrew Tuohy of http://vuurwapenblog.com/ the Aimpoint beat the Eotech.  Eotech has also had issues with battery draining while the optic is off.  Lastly, for a home defense rifle you can leave an Aimpoint on at all times so your rifle is ready to go.  I would not want to have to turn on an optic in a hurry while in an adverse situation.

2.  Will the Colt 901 take any 5.56 upper?

Shawn:  The Colt 901 will accept any 5.56/6.5/6.8/300BLK/etc upper receiver that has a small front pivot pin hole(Sorry, no old SP1 uppers will work with out an adapter).  You will need to use a mag well adapter and change out the buffer and buffer spring.

3.  Aimpoint PRO vs. Eotech.

Howard:  Ignoring the vs. Eotech part that was previously covered, the Aimpoint PRO is an great economical choice for a AR15.  Running about $400 new, it comes as a complete package ready to mount onto an AR15.  At 3/4 max brightness it will run about 3 years continuously.  You can leave this on next to your bed, or in your patrol car and know that it will be ready to go when you need it.  You can quickly adjust the brightness to be appropriated for the ambient lighting condition.  While it runs off a less common battery, you get so much longer life out of each battery it would end up costing you less then if you use an AA battery model Eotech.

4.  What is the lightest bullet for the 1 in 7 twist.

Shawn:  You can go as low as a 40 grain ballistic tip as long as it is a .224 bullet and not .223 hornet diameter, because the hornet diameter bullets have a light jacket designed to explode at a lower velocity.  Hornet bullets will not stand up to the faster twist and higher velocity.  Any quality 40 grain load will shoot just as well as any quality 55 or 62 grain load accuracy wise.  These lightweight bullets are not over stabilized and will not blow apart in flight.  That myth is from the days where people used the older light jacket hornet bullets in the new higher capacity .22 caliber cases like the .223 and 22-250.
