Shot my mosin twice now.... Amazing rifle. BOOOOM-cha-crack. Love it... The only bad thing is my bolt doesn't want to eject my fired bullet casings without using excessive force hitting the bolt to open it. This is with my surplus ammo but new ammo seems to eject just fine. I really don't understand why.
If I ever had to do fast shooting to save my life, I don't think i'd make it.... It takes at least 4 seconds to bang the bolt open with my fist and eject the casing.
This is pretty normal and can be down to any number of factors.
The problem most people jump on is 'sticky bolt' - when there is still cosmoline hiding inside the chamber or receiver, and it gums up the action. It can also be due to lacquered cases on ammo. Sometimes it occurs as a result of problems with headspacing or lug setback... not all that common, though. Best course of action here is a good cleaning, and maybe trying different ammo to see what your rifle 'likes' best.
Another one is the simple fact that you are working against a fairly strong spring with very little leverage, thanks to the straight, stubby bolt handle. As someone with arms like noodles, this is the biggest problem I run into, so I use my fingertips to 'pull' the bolt open from across the top rather than try and force it up from below. Oiling the bolt well may help.
Remember to clean your rifle well after you shoot it, as soon as possible if you're using surplus ammo of any sort. Failing to clean out the bore after firing corrosively-primed military ammo will end in rust. Lots of rust.
