7.62x54r

[mr.e moose]

Hi there; Just a question about the different types of milsurp out there.I bought all of my mosins back in the 80's, and when I purchased them I had bought a wack of Russian snayperskaya ammo.Well I finally ran out and since then I've bought a bunch of Czech surplus.My problem is the Russian milsurp and commercial rounds like privi and S&B cycle fine in all four of my rifles. When I shoot the Czech my bolt binds and I really have to pound on it to cycle the bolt.I have heard that allot of the 7.62 out there is actually a machine gun round and a little hotter so the cases swell more. Is this the problem I'm having or could this be something else?

Its very common when shooting the czech surplus. Google mosin sticky bolt, there are some things you can try to help with the stickyness.

it;s usually because of not so shiny chambers and the laquer on the rounds acting like glue
you can clean and polish the chamber, but the best solution i found was to use commercial ammo with proper brass
