Hey all I just picked up a new 22-250 with 1:9 twist barrel and need some recommendations for powder and loads. I’m planning to run either 69gr Sierra mk or 73gr eld Match bullets. Thanks in advance!

How does the h4831sc compare to like h4350, h4895, or Superformance? (All stuff I have on my shelf)

Which burn rate should I be focousing around? Doing some reading it sounds like folks recommend anywhere from Varget to h1000(seriously?)

I loaded up some superformance and h4350 just to how the powder I have performs

I tried H4350, H414, and IMR7828ssc with 75gr Amaxes in my 8” twist 22-250. Velocity was good but accuracy was lacking. Then I tried R15. Consistently bug holes with groups in the .3 -.4” range and gives me just short of 3300 fps. It’s the proverbial lightning bolt and easily the most fun combo I have.

Try R15.

I had good luck with RL17 and 70 grain Berger VLDs in a savage VLP.
