I want to put together a fast twist 22-250. The reamer I have is a 0.254 NK and I don't want to neck turn necks if I don't have too. If anyone could get me the loaded neck diameter of their Norma 22-250 brass or the neck wall thickness of it I would appreciate it. Lapua is too thick without turning or else I would just use it. Thanks!

The Norma 22.250 cases I have here loaded with Sierra 55 gr GK and 55 gr Norma Oryx measure 0.2497". Lapua cases with the same bullets measure 0.252".

Norma actually makes some brass for lapua. You may want to check if this is the case or not with the 22-250

Norma Brass, is "usually", a bit thinner at, the Neck than, almost ALL other Brass that, I've used.
Neck thickness of Norma Brass, measure around, .013 to .0135 thick.
Put a Bullet in one and add .004 / .005 to determine Reamer needed .
.254 / .255 should be,.. Fine ! But you "may" have to Turn other manufacturers Brass.
Buy, a couple Hundred Norma's and,.. "Choot em' "
I don't Mix Brass anymore,.. as it "can" cause, "Pressure",.. Problems.
