[QUOTE="Greyfox, post: 570888, member: 10291"] As I stated in a prior post, I have had excellent performance and complete penetration on a fairly large sample of deer shot a ranges from 200-1000 yards. The only thing I can think of causing the variable results is something I experienced a several years ago with thin jacked , fast expanding bullets at high velocity in my 270wsm. And the Berger is thin jacketed, take a look at the dent in the bullet if seating pressure is too high. If you have a high velocity, combined with a fast twist and a rough bore, the bullet will leave the barrel in a weakened state and blow up on impact due to a weakened bullet case which actually occurs in the barrel. Its not the high impact velocity that causes the blow up, its the weakened bullet jacket. This is the first thing I thought when I looked at the pictures posted with the surface wounds. 3300 FPS out of a 6.5 with a fast twist imight be too much and turning the bullet into a grenade when it hits. I keep the velocities on my 6.5 with 140 VLD's at 2950 and it performs superbly at all ranges. There is a balance you have to reach if you want to take advantage of the down range ballistics of a VLD. I have not been able to get this balance with other hunting bullets in this caliber. I think the VLD formula works best with heavy, high BC , for caliber , at lower velocities. Just my opinion. [/QUOTE]
