[QUOTE="Mike 338, post: 1382292, member: 41338"] I tried most of those powders listed. Even Varget and it was a tack driver... but velocity was crazy slow. Mine didn't really sing until I tried H-414. Here's some friendly advice though. Find out where you bullet likes to be seated "first" before you begin dismissing powders. Pick a bullet. Pick a powder. Find your max charge weight for that particular powder and load all your cases at about 2% under your max charge weight. Load/Test 5 shots each, at each seating depth of .010", .040", .070" and .100" off the lands. I'll even go to .130" off the lands if the bullet/powder will allow. Shoot for accuracy. Hope you still have a shoulder left! One of those groups will be noticeably better than the rest. Now you can start working up a load. You can even use that same seating depth as a general starting reference when testing other powders as long as your using the same bullet but of course you'll need to determine what the max charge weigh is for each particular powder that you test. As I recall, the Varget shot great with a big jump but was getting 2" groups close to the lands. You don't know till 'ya choot 'em! [/QUOTE]
