IMHO they simply are THE baddest big game bullets in history! They do it all VERY well. This fall will be the third season shooting the 150Lazerhead in my 308 Lazzeroni Warbird (a tweaked TSX). I have YET to have one fail, even when driven at 3800fps. I haven't taken elk with it yet, but it has performed flawlessly on 50+ whitetails, 1 mulie and 1 antelope. Before the TSX came out I shot 130 Xbullets @ 4k fps from the same gun and the only difference between it and the 150TSX was that the old Xbullet would only shoot 1.5" groups @ 100yds. With the TSX I get .5" @ 100yds and 3.5" @ 400yds. I have taken animals from inside of 40yds too well over 400 with it and the result is always the same, get out the skinning knife!

You AINT gonna blowup a Barnes bullet, I have been trying for 5 years with my Lazz. Even double shoulder shots @ 40yds wont do it. Likewise they drive am lenghtwise at over 300yds. I just don't think you can ask for a better performing hunting bullet! I shoot 180TSX (Fed Vital Shok) in one of my 06s and they work flawlessy from it as well (and shoot also .5", but that gun was worked and has always been a great shooter). I wouldn't hesitate to take it for elk and that for sure would be the load it would have in it.

Good luck,
RA
