This post is in regards to 22 Nosler Cases.

I purchased a box of 22 Nosler ammo and pulled the bullets. As far as I could tell with prints and measurements, these cases could be used to make 25 DTI cases (with 223 case heads). I assembled some ammo in my SSA cases and Nosler cases using 32 grains of LeverEvolution, 100 grain Sierra BT and Winchester primers. I had done a rough check on the case capacity with the powder and they appeared close enough.

I shot them at 100 yards and the Nosler cases shot a nice 3/4 in group. The SSA Cases where slightly over an inch, but these cases have been used numerous times without annealing.

The Nosler cases showed slight wipes. Also checked the velocity and the the SSA cases averaged 2750 fps and the nosler cases averaged 2780 fps.

I resized both brands, cleaned in a sonic cleaner, cleaned the primer pockets and uniformed the lengths.

The control SSA group of 10 cases had a weight variation from 111.0 to 113.5 grains. The water capacity varied from 35.8 to 36.3 grains with an average of 36.0 grains.

The Nosler cases (20 of them) had a weight variation of 107.6 to 113.7 grains. The water capacity varied from 35.2 to 35.6 grains with an average of 35.4 grains. The variation of case weight could be attributed to turning the case head down to 223 dimensions.

Whole point of this exercise to see if the 22 nosler case COULD be used. I am not sure how strong the Nosler case head is, but the SSA case has a nice hard head.

Oh --- I just used a bolt carrier with a 223 bolt from another rifle. Worked like a champ.
