Re: Chamber dimensions for a fitted no-turn neck
Thanks for the replies Mike, BH. That was exactly the kind of input that I was hoping for.
In an exaggerated way, the neck are a little like this ( ) - i.e. largest diameter is neither at the case mouth, nor at the neck shoulder junction. By the way, rifle shoots good, but I'm wrestling with runout issues.
Yes BH, compared to the 308 brass that I've measured the 300 WM is really thin. I was surprised too. Winnie as I said and RWS basically the same, although I'll check again tonight. I also have a few Winnie cases I'll not use as I picked them up - will check those too.
Domestic PMP is a lot thicker, but the cases are very inconsistent around the necks and I won't be using them.
For interest I'll post a question as to neck wall thickness under the "reloading" topic.
Yes, I'll measure a bunch thanks and have some buddies check on their micrometers too. That's good advice.
