Thanks for the input guys. I know trying differnt powders, bullets, primers etc....., is fun, however, I am at that point in life (kids taking up most of my free time, a great thing) that I am trying to apply the KISS rule as much as possible in every aspect of life. Later down the road when the nest is empty, I hope to have my shelves full of all types of powders. And before you say it, I have introduced my kids to reloading (my 5 year old daughter loves to help out, my 10 year old son, not too much-just likes to shoot them). To Timw77, thanks for the private message and looking at all my data, I have it down to I4350 and RL22 as to powders that those 3 cartridges prefer.
