Why is my gun jamming?

Question

My rifle is jamming.  I cleaned it after I shot it last a couple months ago and it won't cycle.  Rounds keep stove piping.

Answer

The gun was designed when there were fewer ammo options.  Make sure you're using standard velocity 40 grain ammo.  If that doesn't do it, take it to a gunsmith for a detail cleaning.

Answer

If you're not using a synthetic lubricant, it may have started to evaporate and gotten gummy.  I've seen it a lot with 22's that are "oiled" with Hoppes. Switch to a synethetic lubricant like 5w-20
