300 WSM

[chiefkerdog]

Hey I would like to know if anyone shooting a 300 WSM with a no turn neck what neck size bushing are you using ? Is a .343 bushing to loose for Norma brass ? Just curious because I am going to have to order one or two bushings and hope I can not pull the bullet out after its loaded. Have been using what I got in a trade and have got too much neck tension as it is. Hmm having been winning relays though.

Thanks, Chief

I shoot a 300 WSM and use primarily Norma Brass. I do however lightly turn the necks to obtain uniform neck thickness. Most of the necks before turning are approximately .014 to .0145. I determine bushing size by measuring the neck wall thickness multiply by two add the bullet diameter then subtract the desired neck tension.

Measure a few of your loaded rounds and deduct a thou or 2 .
