Ok, Ok...am I the last person on earth to know about this bullet? And why is it listed under rifle bullets on Hornady's site? I can almost guarantee it will work. There is plenty of room in the chamber, even using .360 Dan Wesson brass. (Which is the brass I'm using) I would call Hornady and ask about the speed that this bullet will perform best, I know I'll be on the phone with them in the morning. Man, something else to play with!
BTW, if you want brass, call Starline and order it. I got an email from them last week saying they would make another run as soon as they had enough orders.
