Ok. So I found a negative of the Pro Hunter. I put my 375 H&H on and went out to have some fun punching holes in 8" thick trunk slabs. I made the mistake of putting my bipod on. The first shot cracked the swivel stud in half. Turns out they are made of plastic. I could have sworn they were metal on my old Encore.
You got me curious so I just checked mine. All steel. I've never even heard of a plastic swivel stud!?
