I try and avoid it at all

I try and avoid it at all cost but there are times when it is necessary. I usually do it when I am down sizing neck sizes such as going from .30 to a 7mm. If I am expanding the necks such as .30 to .357 I usually don't. I guess that is the price that you pay when you are shooting a wildcat or just making brass from another caliber. The nice thing about it is that once you have a couple hundred pieces of brass done you don't have to worry about it for a while.

I just neck size.  Can't see the point in that kind of effort

if you have a match chamber

if you have a match chamber you might have to ream the necks. Normally it's not necessary though. The time is much better spent shooting more. There are a number of different thing accuracy buffs do to get better accuracy. most of then don't have the rifle or the skill's for those thing's to make a difference.

Even when necking down case's to a smaller caliber I haven't had any trouble with thick necks. But it does happen that sizing down does leave you with fat neck walls. I sized down 30-06 cases to 6.5 for my 6.5-06. Got a Forester neck reamer but haven't needed it. Found a better way to make my case's and that's from 270 Win case's. Need to trim them back but that's not a big deal.

I'm suprised a factory rife chamber is that tight, the vast majority aren't.

Turning neck

cases is the last thing I thought about when I picked up this gun. After researching, I found out that less then 5 were made by Evan Mitchell in his garage, one of the founders of Christensen. Evidently, and I had no idea, that he must of made these with bench rest specs. After doing a chamber cast and getting dies made, I thought I was set!!!! Wrong!! Even the fire formed brass differ greatly ( in my opinion ) then the new resized 8mm brass that I have purchased! I am having fun now , after a long trial and error period!! Learned a lot!! It does shoot darts though , so I am pleased!!! Feel better spending the $240 for the gun!! Have about $800 in it now!! Really like the Carbon barrel, even though it is short ( 22 inches) and the weatherby action and frame!! It is nice to carry!!!!
