VG; Near as I can tell from a little idustry "inside" info, its a semi-auto thing...the Remington 597 was a real POS and has been discontinued..
And Mag research has had a couple of their 17 HMR semi-autos go wonky...and I don't think its because of Remington ammo... scuttlebutt is that the 17HMR at times scoots the blowback bolt back so fast that the gases aren't done expanding first, and the back part of the shell is now exposed before the bullet leaves the barrel...makes it go "poof"!
Someone else may be able to confirm or deny this...cause I don't have it in writing, but Ive seen a couple of the guns, and boy, did they go "poof!"
