We'll be cutting the reamer and dies for my PPC soon and I landed on 0.264 for the neck (largely because I already have buttons between 259 and 262). Just interested to know if anyone runs that chamber and what thickness you turn to for short range (100/200).
I was thinking of the following:
Brass - 220 Lapua
Chamber - 0.264" (+/- 0.0005")
Neck thickness - 0.0095"
Bullet - 0.2435"
Loaded neck - 0.2625"
Total clearance - 0.0015"
A 0.260" sizing ring should put tension right around 0.0025".
Thanks,
