M D -
Thnx for your accountS of Sierra bullets from UR experience and observations of others who used them. I readily accept your comments and acceptance of them at least for Deer.
WAY back in the 70s as I was developing handloads for hunting, I literally tested diff makes of bullets in MANY media, from red clay banks, uprooted tree stumps, sifted top soil, mud, wet/dry news papers, catalogs, even SAND.
Don't use sand--- it's like running bullets against a grinder (lol).
I tested 6mm, 270, & 30 cal, consequently, I never loaded/hunted/shot Sierras because I never found 1 (one) that didn't separate.
I would not trust any bullet that consistently separated for hunting game.
I've come to realize that NO medium is the same as animals.
Thnx again
Jerry
