I know lots of folks use H4350 in the 22 Creedmoor but for me it’s a little too fast burning and pressures spiked quick.

I think powders between H4831 to H1000 burn rate are where you will find best performance. Reloder 26 would be magic if you can find it.

I would say Staball 6.5 is about the fastest burn rate I would try and if you need to interpolate data from 22 Creedmoor I have tried just about every powder out there in it so can get you close since the case capacity is pretty close.
