I blew a primer in a M70 Classic .308 (still don't know why) which is supposedly an improvement over the pre-'64, because it has a "gas block" on the bolt that supposedly fills the left lug raceway. Got a good blast of hot gas and a few brass particles right in the face, and was very happy to be wearing glasses. Have had a couple of cases let go in 98 Mausers and only felt a slight puff of hot air past my left cheekbone.
John,
I've looked at that gas block attached to the bolt on the 70, and it "seems" like a good idea but apparently is limited in function. Glad you didn't get hurt. These rifles vent the bolt body to the left raceway, right? I thought the PF post-64 vent to the magazine.
Kimbers vent the bolt body to the left raceway as well which is something I don't understand. And no flange on the bolt shroud.
