[QUOTE="liltank, post: 371936, member: 13275"] +1 to the picking one powder. I have driven myself to frustration with powder experimentation. I just have gotten to a point that I want to go with one powder and make it work. The one thing that I have started doing over the past year is pressure testing. I load 1rnd per 1 grain increment. This is when I try different powders to find my velocity differences. Like in my WSM I did this with H4350. I started at 61.5grns and worked up in .5grn increments to 63.5grns. 62.5-63.5grns shot in the same hole or close to (cutting other holes). So I put together loads of 3 shot groups in 62.3, 62.5, and 62.8 grains. At 200yrds I am shooting .75" with the 62.3 and 62.5. So now I have to put together the loads again in 5 shot groups to verify. I noticed that the 62.3grn gives an 11fps spread, and 62.5 gives me a 7fps spread. Now just to do it one more time for verification. The reason I am doing the 62.3 again is that it may have produced a tighter group. I through it accidentally, so I need to try it again.
