    So I see these 2 powders as popular for reloading 6.5 CM

    What makes one better than the other or is it just personal preference

    I am getting ready to start reloading again and I am trying to determine what powder I should use

    I would look at reloder 16 also if you're loading for the Creedmoor. Personally, it's all I use for mine.

    Big difference in burn rate. Hard to beat the ole reliable H4350 in my opinion.

    Never burned re22, better options. H4350 is very consistent and very temp stable

    Thanks

    It seams to me that it should simple
    The velocity at a safe pressure
    Temperature stability
    Clean
    Economic rounds per pound

    Within reason the latter being the least important

    If you can locate some RE26; I have found it to be every bit as accurate as H4350 and provides a noticeable increase in velocity.
    I rarely hear of anyone using RE22 in the Creedmoor but who knows?

    RL-22 is faster burn rate than RL-26 so who knows. H4831 works for me with 140gr and above.

    As I gather RL-23 is an improved RL-22. RL-26 is supposed to be an improved RL-25 IIRC. I use RL-23 in 6XC. It's pretty slow but makes great velocities with moderate chamber pressures. Great in overbore cases in and 38-48 grain range. So far it's been doing pretty well in 6.5x55AI, .243AI, 6XC and 6CM. I've handed samples out to a bunch of friends and used it myself. Uniformly good results. I know it'll work in a 6.5CM but don't know offhand anyone that's done that.

    My old coach liked H4350 while I like RL-23. We have opposite philosophies on burn speed. He likes higher initial pressure in the chamber, I like higher average pressure. My way leads to more sooting of case necks than his.

    I dunno if RL-23 is supposed to be more temp stable but I got really stable results with it shooting matches in the desert and my ammo baking in the sun.

    Stay way from rl-22. Its sensitive to temp. I'd look at rl-16. If you can find it rl-26 makes some very impressive velocities and is pretty stable.

    I'm pretty sure I've read to be careful with RL26 at 85 degrees and above. Stable until there and then strange pressure spikes have been reported.

    Guess you haven't put it to work in high heat.

    I live in the north east. It doesn't get hot here. 85 is about as hot as it gets.
