The 22 creedmoor thread

[WestTN2288]

I want to change my palmetto state armory 6.5 creedmoor AR-10 to a 22 creedmoor via a barrel change. The barrels from KAK looked like they would be a good option but they haven’t had them in stock for the last few weeks and couldn’t give me a timeframe of when they would get them back in stock. So now I’m considering a custom from deadshot barrel to get a 18” barrel made.

Anyone have experience with either company or advice on whether to wait for KAK to restock or just pull the trigger on getting one from Dead shot barrels?

I’ve got a KAK barrel, but haven’t had time to put it through its paces. I’m just glad to know there’s somebody else thinking about using an AR10 for it here…

what length barrel did you go with? was the shipping or turn around time pretty quick. I think its odd when you ask them when they will have them back in stock they can't provide an estimate.

Mines at 18in. Bought it used from here, so can’t speak to that.

I will say, just putting it together, shooting it enough to get it to cycle, getting it on paper, etc… it shot and functioned well

Cheap Hornady “custom” dies working fine for meView attachment 924607m

Would be a great Rokslide thread if someone wanted to try 4-5 different die sets w everything else being the same and post 20-30 round groups.

Yeah honestly I'm trying to figure out if fancy dies are worth it. I own and use both. Both seem to produce really good large sample groups.
Figure if I go with the cheap Hornady dies I'll have an extra 100 bucks for powder

Pipe should be here next week. Got another newb/'tism question. Got Alpha brass and dies coming.
Should I load up 100 rounds of a mild to moderate charge of something just to break the barrel in? Then start load development? Or would I be ok to start load dev on a fresh pipe and not worry about speed up? Want to have this gun ready to go for my girls for youth days. Which is coming up fast.

Kinda strange no one in Great Falls has factory 22 creed ammo yet. Thought about just buying a couple boxes to atleast get the gun on paper with.

Thanks fam

Scheels should have it. I got my Ruger American 22CM at the Billing store last week and got 5 boxes of Hornady 80 ELDX on the shelf. The deal with Hornady 22CM ammo is it is only available from a Horizon Firearm dealer due to the exclusive agreement between Horizon and Hornady when bringing the 22CM to market and getting it SAAMI approved. It does not show any in stock at Great Falls Scheels though. Might have to order it online for pickup in store.

I would.

I agree, either load some yourself or buy it from midway for break in.

I have 156 rds on my barrel and it’s probably 150fps faster than it was at 0. The speed up happened between 100-125 rounds.

I have almost exclusively RCBS Matchmaster seating dies. I don’t think they make it any more accurate, but the ease of seating with the built in sleeve and long eldm bullets is worth every penny for me.

Ok so I tried 4350 with both 80/88 in my McGowen 16.5 barrel last night and got serviceable groups but nothing to run home about.

One thing to note is I went up to 40 gr of 4350 with 80s on Peterson LRP and got slight ejector swipe but no crazy bolt lift… that’s 2+ grains above book max from Hornady. Does this brass just hide pressure signs that well?

Are there any other powders worth trying? I have 2 pounds of varget but I’ve always understood it burns too fast for heavier that 60ish grain bullets but that could be BS. Is it worth trying with 80/88s?

I'm at 40.5gr H4350, 80s and Peterson brass. Prob not forum approved, but dunked 5 rounds in water and immediately shot w no pressure signs as a pretest for AK next week.
