22 CM bushing size

[Lazer32]

I am planning on running Alpha brass for my 22CM rebarrel. However, I was curious what bushing size people are using? Can anyone give me a neck thickness for 22 CM Alpha brass.

I'm using a .250 bushing with Alpha brass and the 75 ELDM. It seems to work well. I measured some the best I could with calipers and neck thickness is somewhere around .0145 to .015.

Loaded rounds measure .252 on the outside, so .250 bushing gives about .002 neck tension.
