neck bushing

[sevenfal]

Hello,
Am thinking of trying a different neck bushing in my 6BR and need some advice. I have a 265 chamber and am turning my cases to 262 then running them through a redding full lenght bushing die to 261.
I'm thinking of trying a 260 bushing to see if this helps to tighten up my groups. does anyone think the smaller bushing would be to tight? I'm shooting a 95gr bullet with 30.5gr of varget.

thanks alot Sevenfal

Right now you have less than a thousandth of wall tension because of spring back.You state you are thinking of a .260 bushing ,what were you using before?

As I understand the situation you did not mention a critical measurement--that of actual neck wall thickness. A.260 diameter outside with a .010 neck wall will give a different tension than the same diameter with a .080 neck wall or a .012...........
