Anyway I have finished cartridges to be fired as soon as my magneto speed sporter gets here. I'll fire a couple of factory 103 rounds and check FPS on those then start low and work my way up. With the 90 GMX. Anything over 2900 FPS will give me the range and energy I want for a good kill on deer where I hunt.
We'll see what happens.
