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.

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.





Agree totally--the bullet has to be up to the task or sd will not matter for much. Had a similar experience with Nosler Accubonds in a 300 Ultra-mag---velocity was around 3375fps with 180 gr bullets..they had very poor performance on the bigger game and completely exploded the lighter stuff..the accubonds are a good bullet for 3000 fps or less,IMHO..but not much more..

As to all things being equal..would have to reread the article, but think that might be what he was suggesting...
