Ackley Improved Question

I used to just load unformed 223 brass with my 223AI load and shoot. Now, since I found a supply of 1970's surplus Norma 5.56 ammo I just shoot them. They're too hot to shoot in a 223 chamber but just right in the AI. They shoot very well, for surplus ammo, averaging around 1 moa.
My 6mm AI is a little different, and I just shoot factory loads in it to make my AI cases.

send 3 fired cases to hornady and get a hydroforming die.... I have one for my .22-250AI and one for my .338LAI and i have had good results..... Plus you dont have to load them up or go to the range/farm or whathave you to fire them off......

I FF 280 AI brass with new 280 Remington cases and a max load of RL19 and a 140 gr BT
as my gunsmith advised and had no problems.

Shot extremely well about 1.0g below what the final formed load would be.

So, work up a load fireforming the brass at the same time. When you find your accuracy laod, you will add .5-1.5g More powder in the formed case.

Expect exceptional accuracy fire forming the cases. No sense firing bullets in the dirt just to fire form. I fire form while hunting, except on the long range stuff.

Good luck!
