Bushing for 7 mm SAUM

[100FUEGOS]

I have to buy the bushing for my 7mm R SAUM and I do not know which, before the rifle arrives ... what is the usual size of the neck of the standard bedroom? the usual thickness of brass 0.140? I have to calculate a voltage of 0.002 and a chamber space of 0.005.
Thank you.

My go to is a .312", for 9 yrs. But I've used Remington brass, not sure if it will be available to you though. What brand brass are you planning to buy, may help here.

In Europe for 7 SAUM, I can only get brass Norma ...
Thank you.

My last batch of Norma 7 RSAUM brass miked out at 0.0145 inch to 0.015 inch. If you are running a tight neck dimension of 0.315 or so, you'll more than likely need to neck turn your brass to achieve the proper case neck to chamber neck clearance. If you will be using a standard SAAMI neck of 0.320, then a 0.313 inch or 0.314 inch bushing would work. Do you know what your rifle's chamber neck dimension is? - and will you be neck turning your brass?

my chamber neck is .317, loaded ammo measures .312, I use neck turned Remington brass

View attachment 1048069 El cuello de mi cámara, no de la otra parte del mundo, salvo el cuello, SAAMI de 0.320 estándar, porque el rifle es un Sabatti de producción.
Pero si utilizo un buje 313 o 314, el sellado de la cámara será bueno ... pero con un latón miñado a 0.0145 pulgadas a 0.015 pulgadas, y es el que más se puede esperar y no tiene voltaje de proyecto cero.

Gracias a todos ...

Un turned 7 saum Norma brass measures .315-.316 across a loaded round. I use a .313 bushing

[QUOTE = "Alex Wheeler, publicación: 37217708, miembro: 1279612"] Un turned 7 saum Norma brass mide .315-.316 en una ronda cargada. Yo uso un buje .313 [/ QUOTE]
