F-T/R Reamer Spec Review/Confirmation

[MikeMcCasland]

Hey Guys,

Speced a reamer a while ago, and dropped the rifle off for build yesterday. For whatever reason I'm second guessing my own decision on reamer design, and wanted to double check on here before the smith made any cuts on my blank.

Ideally setting this up for Berger 200.20Xs with no-turn Palma brass.

Any major issues you can see? .180FB, .342 neck, 1deg-30, everything else minimum spec.

I would just have him check the throat before he finishes the chamber to ensure it's the seating depth you want. JGS is probably good to go, but it's worth a double check to make sure.

I have a PTG reamer designed to cut the exact same specs. I shoot the 200.20Xs out of a rifle chambered with that particular reamer and they shoot very well. I also shoot 185 Hybrids and 210 JLKs in that rifle, so there are a few different bullets that are fairly optimal for the 0.180" fb. IMO - the 0.180" fb is just a hair longer than it absolutely has to be for the 200.20Xs, but it works just fine. The US F-TR reamer cuts 0.170" fb and a lot of F-TR shooters have been using the 200.20X bullets in that chamber with excellent results. I think you will be very pleased with the results from your reamer/chamber with the 200.20Xs. From my experience, JGS does outstanding work and the reamers I have from them cut exactly what print says they should cut.

Thanks guys! Much appreciated!

Mike , I have a nearly identical print from Dave Manson . Only difference is .010 less FB . Reamers can get weird . Sometimes they'll cut a bit short , and sometimes they'll "pull" cut a bit long . But I see nothing in the print that should be any issue . Blew the cartoon up and compared them , closely . Looks good to me . Not a gunsmith . Just retired Tool & Die guy .

Thanks D-4297! I inspected it closely with a PTG print of the "2013 FTR" reamer, and like you said some specs are a little different, and it's hard to know what's truly important on there. So long as it'll chamber new Palma brass, I can make it work
