I'm planning on throwing a fast twist (1-8) barrel on my beater Savage 12 22-250. I reload everything I shoot and aside from ordering new dies, I don't see a lot of downsides to going with the Ackley over the standard 22-250. Thoughts?

I'm a big fan of Ackley Improved cartridges. If for nothing else, less trimming.
The 22-250 AI is fun.
I always thought the 22-250 benefitted most from AIing. Straighten out the case walls and do away with all the trimming. I say charge on, I was going to do something similar but the lack of ready prefits and barrel life slowed me down. Plus I had 500 pieces of lapua 6br brass, so a 1-8 6br was what I built on that savage action. I recommend Jim Briggs and criterion barrels. My 4 criterions have shot like bartleins and clean up like brux. Plus all 4 were pretty fast, how about a 105 hybrid at 2920 fps out of a 26" 6br that will stack 20 inside of a 1/2" off a bipod prone.
Sounds like a plan. What kind of barrel life are we talking? 2,000? My next step will be finding a prefit and most likely I'll have to order it. I'll have to do some load research as well. Anybody have a good starting point? I've been running Varget and H380 with 50gr VMAXs in the standard 22-250.
Call Jim over at Northland Shooter Supply, he can get you hooked up on a prefit, barrel nut, recoil lug, etc.
About 1200-1500 rds barrel life. That was the general consensus from several guys that had or used to have 22-250 fast twist on 6br.com. 80 Berger at 3250-3300 is going to be hard on a barrel. Seems like h4350 was preferred, so if u don't have any i wouldn't bothering building a rifle that used that powder, as it is non-existent now. Everytime i try to locate h4350 i just get pissed at all the hoarding going on. I have 6 lbs or so left of that powder divided by 5 rifles that use it. I will have several dust collectors if this panic bs doesn't slow down. Gets old seeing people brag on some of the gun forums when they just picked 4-8 lbs of h4350 to go with the 20lba of h4350 they already have. Hoarders probably shoot 500 rds/ye anyway. Sorry rant off.
You could go out of the box and go with the caliber that I am running from GA Precision. It was developed for me by George Gardner and Josh Lapin (Copper creek).
The 22 Creedmoor. We are necking down 6mm Creedmoor brass and using the Hornady 75gr Amax bullet. Im getting 3420fps with no pressure and it feeds perfectly from the AW Mags.
I have had the same bullet up to 3515 with no pressure signs. I dont think the bullet can handle much more speed then that without losing its jacket. To go faster I would step up to the 80gr Berger or down to like a 55gr bullet and really see the speeds come out. I run a gain twist Bartlein barrel, but a 1-8 or 1-9 twist would be fine I think.

6brshooter,
Is your 6BR a repeater?
Is your 6BR a repeater?
Two questions, no flame, very curious:
1. Why invent a wildcat instead of go with any number of "off the shelf" big 22 centerfire chamberings?
2. Why go with the 75 A-Max instead of the 80s?
1. Read the first line of my post..... "You could go out of the box". I wanted specific performance out of a certain bullet. So the 22 Creedmoor was what we came up with.
2. The bullet, at that time, was plentiful and easy to get. We had 1k rounds loaded rather quickly. The barrel twist is nice because you can run anything from 55-80gr bullets and it will handle them all.
The 75gr Amax was the most accurate of the test loads we did right out of the gate.
