Barnes 55gr. TSX Vs. Glass (10.5" @ 150yds)

Hi guys, some of you may know that I have been exploring a recent project of mine which is a MRP CQB 10.5" build and this little test below is part of that.

Basically I just wanted to see how exactly a good barrier round in combination with a SBR would do against glass at a significantly longer range than is typically associated with SBR’s. That is why I decided to run this little experiment @ 150yds. It’s pretty straight forward and I made sure to take quite a few pics so that they could do as much of the illustrating and explaining as possible. At any rate, I got a kick outta doing this small experiment this morning and was surprised that I got the results I did…didn’t have but one chance to do it since I only had the one side window piece of glass.

Test was performed using a MRP CQB/ Rock 10.5" CL 1/7 5.56. Ammo used was the Barnes 55gr TSX. The test was performed at a distance of 150yds. I believe everything else should be self explanatory.

Very interesting, thanks for sharing. I’m contemplating a very similiar build this year, possibly for work use, and I’ve been wondering what kind of penetration I would get against car bodies and glass at extended SBR range.
It looks like the Barnes bullet lives up to its reputation once again.

NICE! Very cool nugget of research.

I’d love to have seen a gallon of water right behind the glass/in front of the phone books.

Doesn’t the angle of auto-glass, in addition to its construction, contribute to penetration difficulties?

Angle of glass is a factor, as is composition–side windows are easier to defeat than front windshields. Also, water is a better medium to “collect” to projectile, than telephone books. Finally, the 5.56 mm BH 50 gr TSX tends to work better than the .223 55 gr TSX loadings.
