How do you size your 7 mm brass?

Well I've decided on the RCBS NS die and the Sinclair comparitor /bump gage body. And a Hornady OAL gage. I couldn't find a Sinclair OAL insert.

Thanks for the help.

Sinclair comparitor gage w/bullet comparitor for CBTO measurements (also stainless steel, not Hornady alum):

Sinclair bump gage to measure shoulder bump. Note these are dependant on shoulder angle, like the Hornady ones, except these are made with stainless steel instead of aluminium:

Do some research look at the type s and then draw your own conclusion.
I did look at them but they're pricy. I wasn't implying that if they were inaccurate or not. I was just asking. I have no doubt that they're the cat azz. Better than I'm gonna shoot:) . I'm gonna take your first advice and get the NS die and bump/ comparitor tools.
