Home Forums Reloading Big Game Rifles FLS die leaving ring at bottom of case?

If you look at 308 reamer prints there .471+ at the .200 line, it looks like you have a pretty small die.
Call Forester and ask them what there 308 FL die sizes at the .200 line. Don't tell them you think you have a problem untill the tell you the answer.

Ok, I'll do that Thanks!

Would be nice to measure with a mic if you live around a machine shop have them measure 2 0r 3 cases or if you have something you know is a true measurement like a pin guage to compare your calipers is good

Yeah that would probably be better. The calipers I bought are MITUTOYO brand. Don't remember what model they are but I've only had them a few months.I have another set I could measure again with.

I have Mitutoyo ones to there good from my testing maybe .0005 of which I believe is in tolerance.
I would start by a phone call now to Forster

I just got back from Academy with a box of Remington Core-Lokt. I've measured 5 of those and they are 0.465- 0.466 at the .200 line. Now I'm confused, my Hornady 10th edition book shows 0.470? First box of factory ammo in about 10 years lol!

Factory ammo will be small at the base, and shoulder because they use new brass.
Sizing back as much as your dies are doing is just over working the brass, there is a few cartridges were it does have to be sized back by .004 like the PRC, 20VT and my 30-28 to avoid clickers with Lapua and ADG brass because that brass is really thick at the web
Factory ammo has to also fit every gun out there.

You can also see .010 short at the datum line on some brasss especially belted brass its why Peterson makes longer 300WM brass.

I think I'll get another FLS Die maybe that will clear up the problem.
