I read that on a bushing neck sizing die you want to get the bushing about .001 or .002" smaller than the size of a loaded round. Sorry if this sounds dumb but how do I get a loaded round without sizing it first. I have some 1x fired brass that I want to prepare. These were not fired in the intended rifle. How do I pick the correct bushing to size the brass? BTW, this is for the RCBS 308 GMM dies. Thanks.

Re: Newbie question on bushing neck sizing dies
Seems to be a very hot topic this week. Look thru the 2 active threads regarding the Redding Type S dies.

Tell me the brass and I'll tell you the bushing to buy, lol.
It's faster this way.
FYI, I have the .332", .333", 334", 335", 336", 338", 339" and .340" for 308 loads, the latter two being step down bushings for my tandemly run Redding neck bushing dies.

Re: Newbie question on bushing neck sizing dies
If you don't have the equipment to accurately measure case neck wall thickness, just seat a bullet in an empty case and measure it. Then simply pull the bullet, resize the case neck and march on.

I cycle a batch of 50 Winchester cases a buddy gave me from some hunting stuff and my .332" bushing will just barely grip the bullet--I'm able to twist them out with not much force.
For most of the 'component' Winchester brass that I have, I use a .334" bushing for ~.002" of neck tension.
This .334" TiNi bushing works for some Federal brass that I have on hand. Most of my Lake City brass, I use the .335" and for Lapua, the .336" works well for most of us here.
You really want to get a range of bushings--maybe not as many as I have, but at least one for stepping down if you have a factory barrel and then a couple/few spread across the spectrum to help cover all of your bases.
~.002" for bolt guns and match loads.
~.004" for gas guns without having to crimp.

Re: Newbie question on bushing neck sizing dies
I will be using LC LR brass. On a side note, after how many firings can I expect volume consistency with the brass only sizing the neck? do I wait for the brass to form before proceed with load development?

Re: Newbie question on bushing neck sizing dies
With the information given, I finally talked with Redding support.
They suggested .331 for Winchester and .334 for Federal. (-.002)

.331" works for some Winchester, .334" works for the component brass you get in the bags.
Always measure Winchester brass to see if you have the stuff with the thinner necks. I mean...measure all your brass, but pay special attention to the Winnie stuff.
Sizing thicker walled brass with a .331" bushing is going to be too much tension, IMO.

For the .308, I measured (.336-.337 on the Federal Gold Match brass and .333 on the Winchester brass)

There you go, that Winnie stuff is thin and a .331" bushing would be in order. Additionally, the Fed. brass can use a .334" bushing like I suggested.
Both yielding ~.002" of neck tension, all other things being equal.

Re: Newbie question on bushing neck sizing dies
I have been using a 0.332 bushing on Win brass for several years.
