Hi everyone,

I posted a few weeks ago about a No4 MK1 rifle that I picked up cheap at Canadianicon Tire. I mentioned that I was having a hard time closing the last inch or so of the bolt - I really had to use a lot of pressure to force the bolt closed. This is without even having a shell in the rifle.

Today I took the rifle out, removed the bolt and cleaned the barrel. The rifling looks fantastic in the barrel still. I removed all the gunk I could from everywhere in the rifle and gave it a light oiling, paying special attention to the bolt and bolt seat. I then placed the bolt back in.

Here's the problem - the bolt now slides forward and closes with much less effort, but it refuses to stay closed. I will close the bolt, leave it for a few seconds, and it will pop open, flying at least 3/4 of the way back.

Did I oil it to much or break something? I could not keep the action closed long enough to aim, and I am afraid that even if I was able to fire it that the force of the shell going off would blow the bolt back into my face!

Any ideas? Thanks in advance.
