6br casing question

So I just came back from actually measuring these loaded casings. They measure out at about .260.... So there you go. Will the case neck have enough elasticity to spring out, or will it self destruct an split the case neck................

Shoot one piece, reload, shoot, reload, shoot, reload, etc...See how many times you can do that. You are likely the only one that can truthfully answer that question.

Riverlife:
if i am reading your post correctly: you said you measure the OD of a loaded round and got : 0.260,
if this is correct, then i assume you are using a standing 6 mm bullet which is about : 0.2435 inches
then using the formula: 2(N) + 0.2435 = 0.260, this would give us a neck thickness of : 0.260 - .2435 = 0.0165, then divide 0.0165/2 = 0.00825 neck thickness to your brass.
that is pretty darn thin necks for a 6mm BR, unless you are running a 6 PPC.
good luck

Well this is why I am asking. However, if you compare this to a 6ppc is it the same or are ppc case necks thinner. Remember it is common practice to take a ppc neck down to .262.
 
Well this is why I am asking. Isn't it a common practice on a 6ppc to turn the necks way down. So isn't it the same thing ?
 
6BR in a trued, blueprinted Remington action. Bartlein 8 twist barrel, no turn chamber. Semi-custom bedded wood stock. One inch Leupold 36x on Leupold rings. Freebore is set for a 105 seated deep in the casing. Remington trigger.

what is the neck diameter of your chamber?

A no turn chamber is exactly that. Usually .271-.272 neck for a 6BR. New Lapua brass usually has a loaded neck diameter of about .269 which will give you around .002-.003 clearance which is good. Some PPC brass is turned to a .260 loaded round because the chamber was reamed with a tight .262 neck. A .260 loaded round is not what you want to shoot in a .271-.272 chamber neck.
