Hi

Just brought a Remington 1100 LW 410 and find that sometimes the Primers come fully or part out of the cartridge when fired and jam up inside

The cartidges once fired also get thrown about 12-15 feet from the gun

Using 14 gram No 9's with 2.5 inch

When I first tried the gun it pulled the primer about every third round, have since hanged cartridge and also fitted new barrle o ring and now fired about 75 cartridges with about 5 cartridges with primer pulled out

Not used to semi but cleaned well before the shoot, Any advice would be welcomed

if it's its not your head space its the problem is with the ammo
