[30EX]

What is the current 30BR Robinette updated reamer of choice right now, and have there been any real changes, what is the go to setup right now, before I talk to Dave and order one, just looking for some input, maybe someone has the current spec sheet to send me, the print out would be nice.

Pretty sure that it's still a .330 neck, zero freebore, 1.5 degree leade angle. Dave will know...or call Randy if you have any doubts about what is his current design. This reamer is the gold standard for the 30BR, but personally, I'd go with just a tad bit of freebore...say .020-.025". Everything else the same. They've been done in several different configurations and most seem to do just fine. You really aren't changing it much by adding a little bit of freebore, and that in itself has some small advantages IMO. ---Mike Ezell

Thats just what I mean, from reading here, there has been a few guys that have banged around the idea and have used different cases lengths and freebore, this comes from using the round and making changes as they go.
Is there a updated print out there to eyeball?

Thanks

Because Dave Kiff sees the ordering trend of the 30BR reamers [at least those orders that come to him] on a daily basis, he has the best visibility of all. He's your best source of the info your searching for. All the info might be readily accessible through a data base search of his files. One of the ladies in his shop can probably help you. They usually email prints within 10 minutes of a request.

when you speak to D R .. your best bet is to Know what bullet your going to use weight - shape 'or the heaviest' barrel twist an length and for what 'yardage'
let him cut you a reamer you'll really need... instead of what everyone else is using...
that was the best advice i got ... we all do use it for different things...
