I just bought a set of RCBS Gold Medal dies for 308 and I also bought the Neck Sizer Die Bushing 336 Diameter. Is this the right neck sizer die bushing for .308 Cal? The brass neck wont go in the bushing.
Thanks

Re: What neck size bushing for 308?
All depends on how thick your neck walls are with a bullet pressed in and your chamber neck size.
.336 and it won't go in ?
Is the brass New ? or Once fired ?
(For me as example ) on my neck bushing for Win. Brass. I use .331
on my Lapua .308 neck I use .336
But on my Win. .300 wm mag. brass I use .333
Rule of thumb I guess is to be about 3-K over the neck OD of brass, with bullet Seated. For Average Tension.

I use Win Brass and it’s been once fired. I measured a loaded bullet (168 Federal Gold Mach) and I got .339 so I deducted .003 and I got .336 that’s why I bought it.
Thanks for your info.

Your right on the money then. Once fired should not just slip right into the bushing. Most Remington chambers will leave brass about .340-341 after firing.
