Probblem with Jammed Bolt

[Neuraleanus]

Are you using factory loads, or someones home-loads ?

150 grain PPU. I don't think the ammunition is at fault. I'm still cleaning out traces of cosmoline. The action has been very stiff making me think that this rifle hasn't been shot in a long time.

I went over the rifle with liberal amounts of Ballistol and that has seemed to help.
