Adjusting body diameter and shoulder bump separately for .308 cases

[Walkalong]

Don't worry, everyone else knows what folks are talking about when they say "bump" the shoulder back XZY amount.

Guffey never wants to explain in his terms how he measures where the shoulder was before and after sizing, or if he just sizes to fit a "headspace" gauge, he just wants to mock other reloaders who call it bumping, and of course his cases don't have headspace, which is technically correct.

So much knowledge wasted because he wants to remain aloof. Sad.

No problem with me, life’s full of tit for tat . I size to chamber freely, load and shoot. I came here to contribute Very simple

My Redding full length sizing die doesn't touch the neck.

Once again, thanks to everyone's comments, I disassembled the Redding full length sizer die and discovered that it is a Type S die. It turns out that I had bought their .308 Match Die set many years ago and never used it. I bought a Titanium Nitride neck sizing bushing at the same time but never put it inside the die itself. I found it still in its original packaging on a shelf.

Once I reassembled the die with the bushing I was able to finally resize the entire case and the neck. I'm still experimenting with the whole resizing operation using the Berden cases out of which I've drilled the primers so the decapping pin can pass through. I'm definitely on the the path to success now, thanks to all of you.

Well, that would do it all right.

Glad you got it figured out.

I would suggest you do some reading up on the whole "S" die process and selecting the proper bushing. I use 5 different sized bushings to properly set bullet tension with all of the different neck thicknesses from the different mfg. of brass that I have.

Glad you figured it out.

Yep, I have Wilson bushings from .264 to .268 for 6MM, plus two more carbide bushings for a .262 Neck Bench gun. I might need a .269, haven't tried the .268 yet, but .267 was too tight with Hornady 6 Creed brass.

I have a few in .22 caliber as well.

You can guess pretty well, especially with feedback from others doing the same thing, but no one ends up with just one bushing.

never put it (bushing)inside the die itself.

Glad you figured out what you had.

I have several sets of the Redding S dies and many bushings. If your using the expander you only need to reduce the min and/or a hair smaller and the expander will return the neck to proper dia. Keeps you from buy a bunch of bushing. Or you can use a bushing so the expander is not needed. I think I have 6-7 bushing for the .224 and 5 for the .264. The next thing you will be doing is neck turning to get them all the same. Then you buy a couple more bushing for the turned necks. You may even buy a expander die too.

I too suspect I'll end up with more bushings to account for variances in brass thickness across manufacturers and lots. The bushing I have now is .332". I used one of the resized Berden cases to test seat a 168gr bullet to SAMMI OAL. Then I put the bullet nose against the bench and leaned on it to see if I could push it further into the case. Nope. Then I pulled the bullet and examined the jacket for scratches. No scratches per se but I could see scuffing where it rubbed against the inside of the neck.

I have the Redding instructions for measuring to determine the correct bushing size to use so I think I'm good-to-go.

Guffy's over on Calguns torturing the reloaders over there about the same can't shoulder bump nonsense. He scours the reloading net to pounce on certain "trigger" words.
