I'm seriously thinking of going with this like Scott has. I have 9lbs H4350 I'll save for my 6.5CM's and look at this for my 22CM. Would you start out near what I loaded H4350 and adjust or start from scratch?

4451 and H4350 are almost identical in burn rate. My testing has shown 4451 required slightly more powder than 4350 did. But, there will be lot to lot variation between each one, so do your own testing and work up.

What bullet weights are you planning on using in the 22CM. If 75gr+ I would be looking at Reloader 26
lf the saying "Liar, Liar your pants on fire" were true
Mainstream news might be fun to watch

I'm using 75gr A-Max, so thoughts say RL26 for this weight? I'm not poking paper or top speed, just the best accuracy to kill coyotes. I'm not looking to be on the cutting edge just dead yotes and maybe barrel life.
