You are correct the Sierra bullets are deigned to pentrate and expansion is minimal. I like there bullets. The 170 in the 41 mag at 1500+ FPS is a very effective deer and anti personel bullet in experience and opinion
Not to hijack JWP, but I agree on the Sierras, 300 gn Sierras from an old 44 mag of mine penetrate like a danged solid, damn tough bullet.
