They do have pistol powders. You may know them by other names. I have been happy with the IMR4895 I got. I bought 8 pounds in a clorox jug for $64. It works just as well for me as the $18/pound IMR4895 from the gun store. They have diffenent ages and pull down. I think I got the worst they had and I can't find anything wrong with it.
I can see if you are shooting .2" groups in competition, you would worry about every variable. My guns shoot 1 1/2 to 6" groups no matter what kind of 4895 I feed them.
