Home Forums Hunting & Shooting Custom Rifles & Wildcats The 22 'ACM' (AntiCreedMoor)

First time at the range today with what I call my '22 ACM' (Anti CreedMoor). Basically, it's a 22 Creedmoor done in reverse of current fashion. Barrel is a Hart LV twisted 1:14 that was originally on a BR gun in the late '70's chambered in 222, then rechambered to the 223-38 by BR great Ferris Pindell sometime in the early '80's. We left the 223-38 and Ferris' name on the barrel for some good vibes. The barrel has been rolling around my barrel rack for years and it was time to get it up and running again. My pal Randy Robinett (BIB Bullets) has a great 22 Creedmoor reamer with a shorter free bore so that got used. The stock has been rattling around on the stock shelf for quite some time, too.

-Mack Bros EVO single shot
-McMillan HBR stock
-Hart 1:14 LV profile
-Jewell trigger
-Lapua 22-250 brass
-Sightron 6-24X44 with 1/4" dot

Other than f-forming the cases, this was the first time at the range. At 38.5 I knew it was clearly asking for more powder. Another .5 gr. and it shot a tidy little three shot group with a hint of the 3 o'clock 12-14 mph push for a bit of a weather report. It hung in there to 39.5 and shot a flat .200. I changed powders and didn't find anything to write home about. Next time out, the 39.0 will get repeated with several 5 shot groups. I don't expect any surprises. The .178 was shots #16-18...it didn't take long to find something it liked.

Good shootin' -Al

neat stuff. Thx for the write up

Beautiful rifle. Makes me wish that gel-coat McMillans weren't bumping $900 these days.....

Beauty. What bullet and speeds you getting?

BIB 52 @ 3,860

Nice fun project

Very cool Al.

Is it going to be a varmint rig or a comp gun?

Cool rifle Al, a Creedmoor with no man bun required. 🙂

It really doesn't fit into any IBS/NBRSA Benchrest class. Just a darn good 'dog gun.

No skinny jeans, either. But I'll admit to wearing Hey Dudes.



Thanks!

That one got settled in a hurry. Cool project.

Speaking for myself, a gel coated McMillan is as good as it gets. If you can do some of the finish work yourself...pillars and bedding, pad, etc, the prices can still be within reason. A basic inlet with just pilot holes for the action screws is what I start with.

My ACM is a 22-250AI, set up very similar to yours, with 14tw. Walther barrel and a big brake, except on a 700 action. Also shoots about the same with 50BT's using just a bit more of the same powder and going a bit faster.. Brass is PMC. In the unlikely event that I need more brass, will make it with 22CM. Nice that it's available with a large primer pocket.

I like that a lot.

I have a custom old-school Schultz and Larsen in 308 Win twisted at 1:14. Shoots 155 Palmas lights out. It's ideal for the 150-168gr bullet range.

I believe in no more bullet weight than necessary for the range used. Longer bullets than necessary only aggregate barrel wear.

The true ACM is the 270 Winchester.

Looking at that rifle again. Love the stock, one of the prettiest I've seen. The whole thing is about perfect.....as a 22-250AI it would be perfect. LOL.

Think of it as a 22-250 AI with a 30 degree shoulder...makes it easier. Using Lapua 22-250 cases helps, too. And the great BR case is on a 30 degree shoulder.

2700, 760 and N540 are on the menu next.

Thanks for the comments.

What makes a 30 degree shoulder easier than a 40 degree 22-250 AI shoulder or the 28 degree 22-250 shoulder if you're going to fire form cases?

Isn't the whole point of the 22 CM to have a standardized quicker twist to allow for the use of longer/heavier bullets than typical 1-14" ROT 22-250s?

A2700 and Win760 along with H414 are the same powder. But you knew this right?
