Thread: Donuts in 243 necks

Turning the OD is way easier to do accurately than an inside ream.

Have a wee go with one piece of brass and measure it up once you're done.

Just the faintest skim off the outside that removes only half the oxidising should do it

A digital vernier should show that you removed half to one thou only

Back off the sizing bushing so that the doughnut is not touched. Solved the seating issue with my 270WSM. My Forster outside neck turner will not clean off doughnuts without cutting into the shoulder.

Good idea. I have a competition seating die for my 7-08 I can throw the 243 bush into. Back off 50 thou or so may just sort it. Nice.
I saw the neck/shoulder being an issue with the Forster too.
