I've used my own reloads and the only trouble I had was the bolt not staying open after the last round ( didn't happen with factory Fiocchi though). I carefully increased the powder charge each time within the guidlines from the Speer manual and it still wouldn't lock back even when brought up to max load. I was using Win 231 at the time and then tried a load using AA#7 at 2/10ths of a grain below max loading and a 124 gr. copper plated bullet and it performed like clockwork. I tried this method using various other intermediate burning powders and they've all worked 100% so far without any feeding issues.
