No Turn 30 BR REAMERS?

[Pete Wass]

Someone or plural must have no turn 30 BR reamers? I am wondering what size necks you decided on?

Thanks,

Pete

if it were me, i would not go with smaller than .333", however, with 30br, I would always skim turn it.
Probably to .0116" or so. That lip on the base of the neck will be much thicker than that if not turned off.

Agree that portion of the neck will pose issues most likely if not turned down.

The quote should say "that lip at the base of the neck will be much thicker than the .333" chamber if not turned down".
You probably wont even be able to chamber a loaded round if you didn't turn it down.

The 'lump' will measure right at .335-.337 when manually expanded. If you don't turn it off, the chamber neck will need to be at least that diameter for a case to chamber...plus the neck clearance you want.

You could get around that with a delumping die and then spec the reamer neck dimension accordingly. Or blow them out in a f-form barrel and go from there.

Good shootin' -Al

I fie formed one yesterday using a 6mm bullet. There is a distinct lump but the one on this case only measures a half thou bigger than the rest of the neck. I realized that would need to be eliminated. I don't mind haveing to ligthly turn necks. But alas there is always something to be done!

I wonder why Alpha doesn't make 30 BR cases??? That would be the cat's rectum.
