In spite of having a lot of press problems I reloaded 100 -9mm and 100 -.40 S&W and shot them yesterday. There were no problems at all. Every shell chambered, fired, and ejected just like it should.
The 9mm were loaded with 115 grain Hornady XTP, 4.8 grains of power pistol powder, and Winchester wsp primers. The 40 calibers were loaded with 180 grain Hornady XTP, 4.8 grains of power pistol powder, and Winchester wsp primers. The 9mm loads are the minimum listed in the Hornady manual and the 40's are 0.2 grains higher than minimum.
I was checking them out by alternating hand loads with factory loads. For the 40 caliber I put 14 rounds in the magazine and alternated Speer 165 grain Gold Dot Duty Ammo, federal 180 grain factory loads and hand loads. The hand loads had significantly less recoil and no flame came out the barrel. I fired one 14 round magazine of hand loads as fast as I could pull the trigger and there were no problems. The gun was a S&W Sigma with a 4.25" barrel.
I did the same test with 9mm and there was no recoil difference I could feel between factory loaded Federal 115 grain and my 115 grain loads. The gun is a S&W M&P 9c with a 3.5" barrel.
