    I’m having a rifle built in 22 Creedmoor on a Remington action with a 26” 1:7.5 twist barrel. Looking to shoot Sierra 80-90 grain and/or Hornady 80-88 grain bullets. Thinking about using Hodgdon H4350 or RL26. Does anyone have any recommendations or advice?

    Reloder 26 will give best velocity numbers. If you want to explore other powders I have tried in no particular order... N160/n560/MR4000/H4350/H4831/Retumbo/Reloder23/Reloder16/Superformance and probably a couple I have forgotten and settled on Reloder 26 because only one reason to build a 22 Creedmoor with a 26 inch barrel....Speed.

    I’m using h4831 in my 22-243 with 75g amax going about 3500. H4350, h4831sc, imr4451 Rl16, rl17, rl22, rl23, rl26 would all be good lots of powders to choose from.

    My dad runs rl-26 in his 22-250 AI with a 95 smk @ 3200 fps. 22-250 AI is similar to the 22 creed. He was able to complete the milk jug challenge with it at 1358 yards. I'd definitely be giving the 95 smk a go. Incredible 22 cal bullet

    With a twist rate of 7.5, I pretty sure the 95 smk will not stabilize. All the twist rate calculator I have used say it will not. Even the 90 smk is on the low side of being stable with a rating of 1.51. I believe with the 90 smk I should be able to reach speeds of 3300 +/- with the 26” barrel. Rifle should be ready in a few more weeks.
