mossy 500 pump

rather chilli in southeastern ontario last night, but not rediculously so.
warm enough that i didnt have gloves, cold enough that i regretted not having gloves.

roughly 1 in 5 shells didnt want to get pulled out of the chamber.

ideas?
 
Sounds like your chamber is oversized causing the shells to expand too much. Strange though because this is usually a remington problem.

huh? if the shells expanded more than usual, would that not allow the extractors to get a better bite on them?
 
It's not temperature related nor is it an oversized chamber problem. Typically a rough chamber combined with steel "brass" and high pressure is what causes those jams. Since you stated you have a Mossberg 500 check your chamber for rust as it is unlikely to be poorly machined and left rough like the 870 Express guns. For most shotgun shells today the "brass" on the base of the hulls is actually made of steel. Steel "brass" expands the same way brass "brass" did back in the day but it doesn't contract the same way or at the same speed, so the steel expands and grabs the rough surface of the chamber and it hold tight! If you search YouTube you will find videos on how to polish the chamber in your gun...it's been explained a million times here on CGN but the videos beat repeating the process again. Winchester "SuperTarget" and "Universal" promo loads in 1 1/8oz. are the worst...and the ones that stick are actually over pressured rounds. If you shoot enough of that $h!+ or are around guys that do, you can tell everytime!
 
i figured it was a temperature issue.

i slammed the action closed tryin to make sure the extractors got a good bite, but when i pulled back they let go

different problem than me then. My extractors hold tight and I can't open the action. I unload the tube then bang the buttstock on the ground to force the action open and the jammed shell out. only happens when the gun is hot, and only with cheap ammo.
 
how new is your mossburg, i had issues with mine when it was new with cheap wallmart ammo packs, i stuck to federal and remington, those and the whitebox supertarget seem to have flimsy brass making it expand and jam in the chamber, find better shells and it will solve that issue
 
I used to have the same problem with an old ithaca 37 and winchester ammo. The brass never contracted back enough and would have to bang the butstock on the ground as well to eject it. Switching to remington or federal and never had it happen again.
 
Yup - cheap ammo but often a good polishing job at the rear of the chamber may fix it...

and it's an extraction problem, not an ejection problem... :)
