The Rossi lever gun I tried in 480 Ruger was a dangerous rifle. The headspace was over maximum to start with, yes it was new. Loading a maximum load from western powders with the same components, the action stretched an additional thirty thousand. I discontinued testing it in that account. I wouldn’t touch one of their 454s.
I designed the big horn armory model 89 in 500 Smith and Wesson magnum. Built two prototypes, shot and hunted with number two. I understand that rifle is in the Buffalo Bill center of the West. Killed an elk with it. My rifle will withstand sixty thousand psi rounds easily. Number two prototype was machined from 4140 and I couldn’t make it stretch or blow up.
What else?
