I have a 1980 760 gamemaster, that I removed the barrel to replace the oring on it few years ago. Shot couple hundred rounds through for it to1" with partions. I was firing this year and I was surprised how hot the the brass was. Note sure if this is just my memory forgetting it normally is or how the gas flows in a pump.
Out of 25 rounds I had 2 split at the shoulder. Last 2-3 I cleaned with rubbing alcohol, all I had on hand.
The brass was shot once before, sized few years ago. I don't remember lube. I tubled in media after sizing. Is lube the cause? Remington, WLR, IMR4350 54.5, noslet seating depths from website.
Also my cleaning has been primarily patches. I did since this, try to get a mop in chamber.
Suggestions on what to check? Should the brass be so hot? Thanks
