Got this in yesterday! Its a navy arms hawken hurricane .45cal with a 1:22 twist for shooting those big monster conicals. Would anyone happen to know the max loads on these rifles? This has one a stainless steel breech plug set up. I've seen some folks shooting darn near 200gr 2f in some of these rifles. Apparently they built them strong. The wood by the breech area is 3/8" thick and around a 1/4" thick along the forearm. Very sturdy rifle!
