[QUOTE="wildcat455, post: 1819378, member: 102653"] There's an easier way to do what you are trying to do. If you have a fired Hornady case and a fired alpha SRP case from that rifle. Weigh both of them, and subtract the alpha SRP case weight from the Hornady. Take the weight difference in grains and divide by 15. This will give you the grain change from one case to the next. From your post, sounds like the Hornady case is lighter, so you'll be subtracting the grain change amount from your original load So we're clear, an example. (Made up numbers.) Hornady case weight 130 grains Alpha SRP case weight 160 grains. 130-160= -30 case weight difference. -30/15 = -2 grains. Reduce your original load in the Hornady case by 2 grains for the new case. That'll put you close to your original velocity. If case weights aren't that far off, you can use for every 1.5 grain of case weight is = to .1 gr of powder. Notice that is .1 as in 1/10th grain.
