Anyone tried N555 in the 22CM?
It's pretty much the same burn rate as H4350. It will work

Yeah my experience with N555 indicates the burn rate is close to H4350, maybe a touch slower. It does give a better case fill % in my 6.5x55 than H4350 working at similar pressures. I like it a lot thus far.

Currently using it with 88eld. It's about perfect for burn rate/energy/case fill. It's burning slower than h4350 and giving me 50-100fps more velocity
How temp stable and clean has it shown to be?
n570 improves velocity…but it's so dirty it's not worth it to me (in a 30 Nosler, clearly a different animal).

I found it to be temp stable in my 25 creedmoor. No unexpected pressure signs, and impacts were expected from over 100 degrees to the teens. Great ES/SD as well. I don't really clean barrels anymore but it doesn't seem any more or less dirty than h4350
I'm assuming it's good to go in the 22 creedmoor but do not have extensive experience with it yet. Had about 600 rounds through my 25 creedmoor with it for reference
