Thread: 222 from 223

Rambo: thanks for that. I thought about using 223 brass to make thicker necked 222 for an over-generous factory 222 chamber (must be about 0.256" in the neck diameter). But as the difference between your PMC factory load neck and a reformed 223 case is zero, I don't think I'll bother. Incidentally, by my measurements of the reloads I have: Lapua 222 loaded rounds are the largest diameter at about 0.250" and PMC the smallest diameter at about 0.246" (I must have a completely different lot of PMC brass from yours). Also, I found PMC brass to have the most consistent neck thickness out of Lapua, Sako, Norma, and the Nth American brands (Win, Rem, Fed, Imp).
