22 ARC Begins

[SKWERLZ]

Another promising 22 arc powder is stable 6.5.
Good case fill.

I tried the StaBall 6.5 but wasn’t impressed at all with groups or velocity. I’m thinking TS15.5 for velocity and case fill. Maybe Varget but I just hate how slow the loads are before pressure. Maybe N540 will work

I am. I missed that. My 22 BR barrels all maxed out about 1 grain lower: 32gn for 90SMK, 31gn for 95SMK. I need to check my notes but I was shooting the 95 at 2950 below max velocity and can push the 90 SMK up to just about 3100. All that to say you should see a lot more speed than you’re getting before maxing out. My first rounds down a new barrel are always disappointingly anemic, but speed comes right up as I work up the loads.

I’m excited to see where you get with it!

I’m kind of surprised that H4350 works well in this cartridge. I would have figured it would be too bulky and slow. I guess I am always learning! Lol.

I have a 6ARC and I love it, so naturally I am eyeballing this cartridge as well! Just out of curiosity, would this cartridge have a liking for Leverevolution too? Or would that be too fast?

According to Hornady, 22 ARC like Lever and CFE223 much like 6 ARC. All fine and good if you aren’t after a temp stable load

IME, LVR makes good speed but I have not found anything with it that excites me for accuracy...fwiw.

I need to try 8308XBR in my 22Arc
It’s my fav for heavies in 223.
6.5 stable is showing promise, probably not ideal in a bolt gun but in a gasser I can get the speed I want and initial accuracy seems good.

CFE and lever get the speeds but accuracy was meh as was ES.

I hope to tryN540 at some point.

IME, the 8208 is just the opposite of the LVR. Great accuracy but pressures out before making great speed. That's in both a 6 Grendel and a 22 ARC/Grendel. I don't recall trying the 6.5 in either yet.

Yea
I’m thinking of trying 8208 with some 69smk’s just to see how good this cheap green mountain blank can shoot.

My main load will probably still be 6.5stable/80eld.
