Barnes TSX ( triple shock X ) 55 grains Test Part 1 in a series

This is the first in a series ( I hope ) of test i will be doing on some of the barnes TSX bullets in a variety of weights ( my wallet allowing) and through a variety of barrier. These first rounds were fired from a  16 inch barrel carbine   through a car front window and  into a IDPA target then into a stack of 5 large phone books.  Rain destroyed the target and almost my camera before I could get pictures. But here is a few pics of how well the  TSX bullets performed.

The target was 50 yards away and I faced the window head on. After passing through the glass the round stayed on course and went trough the exact spot I was aiming at into the IDPA target that was about two feet behind the inside of the glass. There was no key holes or any signs that the round did anything other then what it was meant to do. The bullets then went into the phone books and traveled  through 4 before stopping. The books were about three and and a half inches thick each.  I dug them out to find that they  had shed no weight that I could measure and had not shed any “pedals”.  I also did not find that any of the points had sheared off or collapsed in on itself causing the bullet to fail like has been claimed can happen.  The ammo was factory corbon brand.

The next test will be handloads since factory ammo is cost more then a hooker made of gold.

Next up I will try the 62 gr followed by 50s, 70s,and 53s.  Last year I should note, I killed a deer from 150 yards away with the same gun, using the 70 grain TSX. It dropped with one shot to the left side shoulder. The round went all the through  and I could find no bullet to examine. Exit wound was the size of a quarter. I have been a admirer of the TSX bullets for many years but last year was the first time I used any one meat.

Hopefully the future tests will give and idea of how they perform around vehicles. I hope to get an idea how useful the bullet would be for police officers in a situation that involves  shooting around cars like on a traffic stop gone bad. Of course police spend a lot of time around vehicles so it makes since to have a round to  go through most barriers of cars and still have what it takes. Hopefully I can dig up an old engine block to see try them on just to see what happens.

On the Side Sling swivel

Occasionally questions arise about the side sling swivel for the AR15/M16/M4.  This will answer a few common questions.

It is normal for the sling mount to move.  it will wear and make marks on the barrel.

Side sling swivels come from the factory mounted so the loop faces the rear of the rifle.  This is fine if your using CAR or M4 plastic hand guards.  However if you are using a Knights M4 RAS this loop will interfer with installing and removing rail panel covers.  The Army authorizes mounting the sling loop forwards to negate that issue.

If you are mounting a M203 underbarrel grenade launcher on a M4, the side sling swivel will need to be mounted so the loop is on the ejector port side of the rifle(same side as used for left handed shooters).

Suppressed Sig 556

 

I had the opportunity to examine and fire a suppressed Short Barreled Sig 556 with an AAC M4-2000 can.  I did not like that setup.  It’s owner pointed out that the mount of the AAC can prevented the gas system from being removed for cleaning.  When the rifle was fired, gas would vent from the gap between the Sigs upper and lower receivers, and blow upwards into the shooters face.  Later in the day, the owner of this rifle ended up having mechanical issue with his rifle.  He ended up having to take it home to disassemble it for cleaning and maintenance.

The SBR Sig556 and the AAC M4-2000 does not make for a good combination.
