I posted this on another forum that we probably all belong to but I figured I would post it here too.
I have been shooting and reloading for 10mm for a little while now and typically use Longshot and Power Pistol, occasionally HS-6 but it meters poorly and jams up my measure.
I have both the Lee and the Hornady reloading manuals and both call for Accurate#9 or Blue Dot for full power loads. However when I look at the pull-downs from the boutique ammo manufacturers they seem to overwhelmingly use Longshot or IMR 800x.
What gives? Why do the bullet manufacturers reloading manuals list Accurate#9 and Blue Dot as the top performer but the guys who actually manufacture 10mm ammo get better results with Longshot and IMR? Why do they list comparatively anemic loads with Longshot? I was looking through another manual (Speer I believe) at my reloading store and that manual also calls for Accurate #9 for the best performance.
For what its worth, I have not worked with IMR 800x but I am fully aware of its poor metering properties. However Longshot meters great.
What am I missing?
