I was wondering if anyone out there has had any difficulty with Olympic 7.62X54R in the their M44 Mosin's.
I've got a bolt that was pretty tough to cycle and I was trying to find out if this was the ammo or something else. I've been looking through other postings and it looks like it is probably the ammo as Brown Bear has never given me any difficulty. I don't want to damage the rifle if it is a pressure issue, so any input from folks who have experience with the round would be appreciated.
Thanks in advance
Brendon

Bump and additional info.
I shot the rifle again last night with the olympic and some silver bear ammo. The bolt only jams up after firing with the olympic. As long as it isn't fired the ammo cycle and ejects smoothly.
I also tried the ammo on a finnish mosin and it didn't jam the bolt, but it was a little more stiff when cycling.
Any assistance would be helpful. I don't want to destroy the rifle and I've got 500 of these olympic rounds.

I don't have any experience with Olympic, but, have you tried cleaning the chamber? I mean really cleaning it? There could be a bit of lacquer built up in there and for some reason the dimensions of the Olympic rounds are just a tad larger and with any buildup that could create the binding you're experiencing. Mosins are notorious for the sticky bolt issue, and usually it is caused by lacquer buildup in the chamber.

Thanks for the suggestion and the site. I've been pouring over different info to try to figure this out. I went to Wally World yesterday to pick up supplies to really get at the chamber. The site you suggested is highly recommended, but since I'm at work I can't open it. I'm not online at home, so I'm going to have to go to a friends or something.
I do have a follow up question that I'm a little embarrassed to ask. When you say clean the chamber, are you referring to the area that is covered when the bolt is closed or are you talking about the initial section of the barrel where the round sits prior to being shot?
Thanks in advance

Olympic will cause your gun to do that. It's not the gun, it's the ammo. Stay away from that stuff and just feed your gun the cheap surplus. :) It'll thank you for it.

The area in the barrel where the round sits immediately in front of the bolt.
