GP100 bought years ago used. Never had a problem using factory ammo: Remington, Winchester, Federal (American Eagle) ammo, .38spl and .357mag.

Started reloading this year, and initially no problems. Typical reloader, not saving money, just shooting more frequently. .38spl mixed used brass, light loads of Bullseye and Remington small pistol primers. .357 296 Winchester, new and mixed used brass, CCI small pistol magnum primers. Hornady XTP jhp and some cast lead bullets, 158 grains. Don't believe ammo is the limiting factor in shooting effectiveness, so not trying to "improve" on published loads, and I have weighed every charge. Bullets all built on a Forster Co-Ax press, and the press is used to seat primers.

I'm getting light primer strikes on both the .38s and the .357 reloads. Single and double action. 2-3 per cylinder. Factory loads are flawless. A friend provided reloads for me to try, and his reloads were unreliable, while mine fired from his gun. I thought maybe a previous owner swapped to a light hammer spring, so I ordered a Wolf set and installed the heaviest 12# hammer spring, and no change. Also, my initial reloads were also flawless, this is a new problem, last month or so with reloads only, but both his reloads and mine, .38spl and .357mag double and single action, Remington and CCI primers.

My friend also mentioned that I might not be seating the primers deep enough. Forster says the press will do it properly, visually I make sure they are recessed below the brass, and I've been running the ram teice for each primer (and handeling them with tweezers).

Any suggestions?
