300 win mag neck OD loaded round

[PAshooter20BR]

Does anyone have a measurement of neck OD for a Norma case with a Berger hybrid seated? I'm trying to size a bushing for a die.

Thanks

I run that exact combo , mine measure .335"

Do you run a bushing die for sizing down your necks? What size bushing are you using - what's your neck tension?
Thanks

I use RCBS FL dies for my 300 WM , can't help you out with a bushing size.

Same combo, I run a .334 Redding Type S bushing setup. Loaded diameter is .336 to in my case. For some reason with my Hornady bushing dies I need to drop .002 to achieve the proper size. Ie. a .335 bushing sizes to .337... but my Redding die is spot on.
