How safe is Milsurp?

Just a question to anyone. When you buy a Milsurp, how do you know if it's safe to shoot?

I don't want the barrel exploding on me or something.

I have a 1944 Long Branch Lee No 4 Mk I that someone gave to me. I had to give it a good cleaning. The bore looks pretty good, but I'm no expert.

Also bought a Russian M44 Mosin Nagant recently that I want to try.

Please help with your thoughts on how to check that the firearm is safe to shoot.

Thanks in advance.

I've never worried about it, but if you are, the safest bet is have your local gunsmith check out the rifles for safety.

Thanks for the advice.

I was never to worried if the rifle had matching numbers on the bolt and the action, even if that had been renumbered by some arsenal. If I obtained a mismatched rifle I would be more careful and make sure the head space was good before firing. I know that this is not a guarantee but it helps my confidence in the rifle.

On Lee Enfield rifles, one must ALWAYS check to be sure that both lugs are bearing evenly if the bolt is mis-matched. They almost never do on mis-matched rifles, even if the headspace is okay. The rear locking Lee action can be dangerous if only one lug is touching.
