10mm reloading

[RHTK812]

Any good mixes you want to share with a new 10mm loader?

Any particular bullet weight you are looking at? I prefer Accurate #9 for anything for 180, 190, and 200 grain bullets, and Power Pistol for 135 and 155 grain. I just finished working up some subsonic loads for my MP5, 5.2 grains of Universal, 200 grain TMJ's. Unfortunately, this was the last of my Speer 200 grain TMJ's, and they don't make them anymore. My plan is to get some plated 200 grain bullets from Xtreme to replace them.

My favorite powder for 10mm is Longshot. My loads are all 180 gn. bullets, XTP's, Montana Gold flat point and hardcast lead flat points. I'll look up the powder weight tonight and post here but it's near the max listed in the Hodgdon manual. Crono right around 1350 fps out of my 6 1/2" S&W 610 which is a very close approximation of the Buffalo Bore loads. Have no idea how they perform in a semi-auto.
