[QUOTE="screech, post: 1113334, member: 5135"] I'd pick the bullets you want to use and seat them to where you want to run them first. In other words if you want them to fit in the magazine make them fit to that length. I'd run the powder you want to use. If it was me I'd try h1000 but you can try retumbo. Start at a mid load on the reloading manual then work up until you get pressure signs. I generally just run 3 shot groups To get something close.you should see your groups open up and close if your gun likes the powder. Generally this only takes 5-8 groups. With the size of case just use 1 grain increments. If it doesn't come up with something decent try a different powder and start the same process. If you don't find something within say 4-5 powders switch to your second bullet of choice and try again. After you find a bullet powder combo your gun seems to like then you can do additional tweeking if you like but generally this will get you a working load. If you need help pm me [/QUOTE]
