[QUOTE="jdyoung, post: 1881041, member: 113391"] Chrono the rounds, save at least 5 unfired of the brand with the best group and take them apart, weigh each individual charge. Get a computer program, I use Quick Load (the only program that would let me do this simple task as written below). Enter all the pertinent info you recorded about your fired factory rounds, (bullet type weight, brand; primer type, brand; case brand etc.). Go through the powder list without changing the charge weight until you get a load with the same velocity (or in the ballpark) as you recorded about your factory rounds. With powder, I pick a powder that is manufactured by the same company as the ammo manufacture. By example: From a marketing approach, the makers of Remington ammunition would be stupid to not use DuPont powders. But each manufactures policies are going to be different. The above program will tell you if the load is safe, (I stay away from compressed loads, it will tell you if the load is that) I’ve done all this. Saved me trips, travel time etc that I couldn’t afford to the range, as it's not in my backyard. The last time I did this, without adjusting the scope, the reloaded group was at 6 o-clock, -1.6” from the factory group @ 100 yds. I increased the charge, checking it for safety with the computer program, and it walked right on top of the Factory group. [/QUOTE]
