    I've noticed since I purchased this gun back in 2002 that with lighter loads such as Rem 1oz games loads the primers look barely dented. Yet when I shoot turkey loads, slugs or buckshot the primers are always well hit. Has anyone else with mossberg 500's had this issue? and is it something I should worry about?

    So long as it goes bang don't sweat it. Could be thicker rims on the heavier loads don't seat as deep in the chamber making for more of a divit, could be softer vs. harder primers, could just be the heavy load recoil shoving the shell rearward into the pin.

    The heavier loads put more pressure on the primer, and it flows backwards and conforms to the firing pin more.

    Assuming you've got the trigger group and the bolt and everything clean and lightly lubed, and it goes bang, you're probably fine. Doesn't take a lot to ignite a 209 primer.

    Had this once with mine. Took it all apart, cleaned and lubed it and haven't noticed it since. The gun had been in storage for a while. I put it away clean and lubed so thought it was gtg. After noticing the light primer strikes I took it all apart and found that the Rem oil had varnished the firing pin.
