Need some input on reloads

Great ,, hope that works out for you.. I've found the Sierra manual has very good gas gun chapters ... Speer book also has some good tips on military caliber gas loads ... Cheers...

+1 on pressures and cartridge headspace...

OP, do you have a comparative headspace figure between say a fired M193 load and a FL size case?

You might want to try bumping the shoulders a bit less, minimum for reliable operation... I've been able to get away with about -.0015" to -.002" on my autoloader.

I don't have a comparative headspace figure for M193 and FL sized cases. I will have to check that!

Update: This weekend I took the original loads out to the range and fired them out of a clean chamber. All the cases ejected clean. The only thing that I can think of is that I was using a brass catcher when doing my testing originally. I also did some load development with CCI 41 primers also. I settled on a good load that gave me just under 3K FPS from a 20" barrel.

Going to switch over to CCI 41s and keep things on the safe side. Thanks to everyone who contributed to this thread.
