I've got a new build from Jon Beanland in 6.5 SAUM. I asked Jon to use his "no turn" reamer which has a .298 neck diameter. What is my best route to prep 7mm SAUM brass? Buy a full length 6.5 x 300 saum die to resize and roll?

Sounds nice.

Pictures?

Maybe Pat or others using this round will answer.

Very nice.

What glass are you planning to use?

Sweet!

Jon built me a 6.5 SAUM with ,298 neck
I bought some dies from Copper Creek

Anyone else got any comments/thoughts/opinions?

You'll need a .311 bushing if you use .300 SAUM brass to start the neck(first step), then size again with a .295. If you're using 7 SAUM brass, neck it down first with a .295, then run it through a .264 diameter expander mandrel. This step will get you the correct neck tension, and get you better run out. Trim to 2.025" de-burr, chamfer, load and shoot.

.300 SAUM brass will finish at 2.010, so you won't have to trim for quite a few firings.
