I am making some 6.5g from 7.62x39r.
This is my first go round with making different calibers....case forming.
I read quite a few articles that said you may need to neck turn some brass.
So far, I haven't found any that really need it.
But, being the compulsive spender that I am I got a neck turning attachment for my case trimmer.
And a pilot for 6.5mm. All that I've read says you ream/turn AFTER sizing.
That brings me to my question:
If you size the brass down to 2 or 3 thousands bullet pull, why would you want to ream with a bullet size reamer?
Wouldn't that eliminate some squeeze/grip from the brass on the boolit?
The pilot/reamer I got from RCBS was .264, same size as the boolit. not really boolits, I'm using the condom bullets for right now.
Seems the reamer ought to be .261 or .262.
Can you straighten me out?
