Neck Tension Question

[ConRich]

I read somewhere that when loading for the 30BR it is best to seat the bullet with a lot of neck tension.

My loaded round measures 0.3275". What size bushing should I use ?

TIA,
Dick

I'd say go .003 - .004 under loaded round for bushing diam...
So a .323 - .324 bushings.

My set-up with a .334nk, seated bullet measures .3322 neck diam. I FL size with a .328 / .3285 bushings. Fairly stiff bullet seating but it SHOOTS!

Good luck,

Good advice. More is better wif 30 BR's.

Thanks guys, I bought the .323" bushing about a month ago but wasn't sure about useing it. I thought that it might be a bit too tight.

Thanks again,
Dick
