Daryl is right.

I've tested high SD bullets that penentrated no more deeply than bullets with much lower SD's. Just because a bullet has a low SD doesn't mean it will automatically penetrate less.

All things equal in two bullets of identical construction, SD means something. As a guarantor of penetration in and of itself, not much anymore.

One thing a long, heavy lead-cored bullet does have going for it is just that, lots of lead available for fragmentation. Some somewhat "weak" longies like the .264 Hornady 160 grain bullet are fast killers on light game because they send fragments out for quite impressive wounding effect.

But with big mean game, forget it.

Make sure the bullet is up to the task.

Personally, I don't blindly "trust" any maker anymore. They all make losers from time-to-time, and don't warn you when they do.

Pick a well-known top performer or devise yourself a test to match unknowns against knowns. Don't rely on engineering specs or advertisements. Period.
