Die blank reaming question.

[ImBIllT]

Building a wildcat for f-open. Happened upon a reamer for the cartridge that I wanted at a good price. Bought a Wilson seating die blank. Just realized that my solid pilot on my reamer is .256" and the pilot hole in a 6.5mm die blank is .264ish. Do I have to use a removable pilot reamer to match the pilot hole to get match grade results?

Hopefully your reamer is for a cartridge and not just the caliber.

There are different styles of reamers based on the work you want to accomplish. Chamber reamers, and die reamers are the most used outside of neck/throat reamers. You have the same dilemma with die blanks, which job are they supposed to accomplish? It sounds like the Wilson die you purchased is for a Seater die and not the sizing die. The reamer you bought sounds like a standard chamber reamer and not a sizing reamer. I could be wrong of course because the amount of information is minimal.

Regards.

Yep. Poor wording on my part. I bought a solid pilot chamber reamer for the cartridge that I wanted. Then I bought a Wilson seater die blank, not thinking about the descrepency between my solid pilot size and the size of the seater stem. There are lots of threads discussing the use of chamber reamers to make seater dies, but none mention anything about pilots.

Yea
You may have to sell and or trade your solid reamer for a pilot reamer with the appropriate bushing

If you prebore the hole with a boring bar to make it straight and round...the reamer should follow it

It may be more cost effective to chamber ream a barrel stub, and buy a .2645 reamer to make a seater stem hole.

Dave Manson can and will alter solid pilot chambering reamers to use removable pilots. I think the cost is about $30 + shipping both ways. Turnaround time is usually very reasonable.

I think I'll just be going with this route for now. If the gun doesn't shoot, I'll check run-out on the loaded ammo first.
