Bullets that well advertised but were not that great

[Green Chile]

I have been working up a load for my 6.5 PRC (New to me rifle) with Berger Elite Hunter 156 grain for Red Stage, Sika Stag & Roe Deer this fall in Scotland.

In your experience, am I going to get into trouble on shots say under 200 yards that these bullets might not hold together? Berger claims the following but I was going to call them to discuss what I should expect from the muzzle to 400 yards using these bullets.

J4 Hunting Jacket​

J4 Precision Bullet Jackets are the #1 choice of custom bullet manufacturers. They are the most consistent and concentric copper jackets in the world holding an unprecedented +/- .0003” tolerance. J4 hunting jackets are produced slightly thinner to allow for 2-3″” of penetration before rapidly expanding, producing extreme hydrostatic shock and a massive wound cavity.

All of my Berger kills were with the 6.5 PRC or 7 STW. Longest shot was around 250…shortest was about 60. I would say their description is correct. You get a few inches penetration then rapid expansion with no exits. Stay away from shoulder bones. I hit an aoudad in the spine and it turned spine into pea sized gravel.
