I do recall a fellow on another forum, dropped his large cougar using a Tracker 4" w/170 JHP Sierra's, mid range load around 1150-1200 mv IIRC.
Good info above guys. Bob, appreciate the twist comment also.
I emailed with that guy who killed the cougar with the Tracker as I also have one of them and was interested in his load... It was pretty light and the bullet didn't hardly expand at all.
Most shooters don't realize that the Sierra HPs are made for hunting...as in high velocity impacts. The 170 .41s and 180 .44s don't "blow up" on impact as many think. I hit a deer in the chest coming almost straight on at 30' with a 180 .44 coming out of a 7.5" Redhawk. Velocity was 1700+- fps. Turned the heart to Jello and broke two ribs on the way out...a good 18" of penetration. Gary Reeder has used the 170 .41 in his .41 GNR (.44 Mag. necked down to .41) to take elk.
