What gauge?
If 12 or 20 try Winchester AA ammo or Premium Remington Ammo.
Also some have polished their chambers and had good success.

I had a brand new 12 gauge Remington 870 Express with such a rough chamber shells would occasionally hangup. I believe I first went over it with a automotive brake cylinder hone (available for maybe $10-15 at NAPA). and then I took a 10 gauge bore brush wrapped it in steel wool and dipped it in automotive rubbing compound (the orange stuff) and spun it in the chamber using a powder drill. The chamber soon had a high shine and I had no problems with sticking shells after that.
