Ackley Improved Question

At the risk of sounding stupid, I just want to make sure I am doing this the correct way and/or the best way.

I have a 25-06 AI barrel coming for a Savage build. This is my first Ackley.

To form fire the brass I can simply

1) run the 25-06 Rem brass through a full length 25-06 AI dies, and prime the brass

2) load some cheap 25 cal bullets with a minimum load

3) shoot up the loaded rounds

4) run the newly formed 25-06 AI brass through the 20-06AI full length dies

5) start load development like normal

Did I miss any thing or is there a better way?

In my experience with 25-06 ackley I loaded a middle to upper end load to form my brass. It also helped me get used to how the rifle shot. I even loaded some nickle brass and they formed really well.

good luck

P.O. Ackley recommended that you shoot full power 25.06loads to fire form to 25.06 ai

I find a mid to upper range load with the heaviest possible buyllet and the fastest possible powder ,i have found that this works very well and full sizes the brass.

In a properly cut Ackley chamber the bolt should just close a bit more snug on a standard 25-06 case then the Ackley case. The desgine is so that their will be no headspace issues with shooting factroy loaded ammo in the gun , which is a good way to get used to the gun and fire forme brass at the same time

I have been told by quite a few guys that you can successfully fire form with a small charge of Blue Dot pistol powder and a wad of cotton in place of the bullet.

The idea being that the extremely fast powder will blow the shoulder forward and you wont burn up your barrel prematurely by fire forming rounds out the business end of your rifle.

I will go out to my shop and try it right now and let you know what I come up with.

Ok, It worked well with 20 grains of blue dot. I think that I would go up 5 more grains though. Just to make sure the sholders form sharply.

# 1 Run your new brass through a standard 25-06 die as it is not yet a 25-06 AI.
#2 Load some cheap bullets at upper middle to max 25-06 loads.
#4 Run your new fired formed brass through an FL die or a Neck die. In my experience the AI's respond well to neck sizing. You can neck size with a standard Lee 25-06 Collet Die. They work great and are cheap.

I don't bother with that stuff with my 243AI varmint rifle. I just run new 243 brass through the 243AI FL sizer die, chamfer the case mouth and load with a grain less than the full AI load (with the bullet kissing the lands). These loads are as accurate as the full house loads, just a little slower. The varmints won't know the difference.

After you've shot these "fire-forming" loads you can neck size (for the next several firings), and you need to adjust your scope for the different POI of the full load.
