Anyone else have issues with the factory pistol brass from winchester? I am loading for .45 gap. I load XTP, coated, lead, FMJ and copper plated projectiles in 185 gr and 230 gr. I use a chronograph. When I Ioad at higher velocities, the winchester brass always shows signs of pressure (glock bulge) way before my other brass (Speer, Remington). It's a big difference too, sometimes as much as 100 fps difference in how much hotter I can load the non winchester brass. These are all brand new cases from Winchester. I have other cases that have been loaded 5 and 6 times already and they show no signs of pressure. It does not matter what powders I use either. Happens with power pistol, BE86, unique, cfe pistol, etc. I was going to try bullseye and american select, but ran out of XTPs (ordered but backordered). I have come to the conclusion that I have to use the winchester brass for my medium to light range session reloads. Anything hotter, I am just throwing away brass after one shot.
