I finally shot through my stash of 10mm reloads and am now back behind the press. It has been almost 3 years since I loaded any 10mm's. I was on an 38/44 then 357 Maximum kick for part of that so they took the bulk of the reloads. Then came the 38 supers and now finally I have come back to the 10mm. I think I have 5500 pieces of brass to load right now. I will be at it for a while. I will comment that I am having great consistency with my 800x. Once I got it dialed in, I was getting 9 grns to 8.9 grns on every through. This is a nice accurate lead round plinker load I like to shoot. I read the posts and think 800x is going to be a pain but every time I use it, it is very consistent on my Pro2000.
