    Looking at the Alpha Munitions website they recommend a measurement of .470 to .4714 at the 0.200 line. The reamer print I got from JGS (#1297) for the David Tubb reamer is .4695 at the .200 line. Difference of .0005 if comparing to the lower end of the Alpha recommendation.

    Is this significant and what issues would a person have if they used Alpha brass with the JGS #1297 reamer?

    I have heard that Peterson brass is going to make 6XC brass fairly soon as well but not sure which reamer it would work best with?

    Finally, the .090 freebore is best for which bullets?

    Thanks.

    I don't know if it's significant but the reamer I got from JGS (per my request) was .4705 at dimension B. And I got a lead (T&V) of .1280 for 105 Hybrids.

    I have a CIP spec reamer from PTG. Works well (at least with Norma brass, will try Petersen when it becomes available). Instead of thinking about small differences I went with the standard used by European target shooters

    I have the PTG reamer that is .470 @ 0.200 mark and .090 FB. I use a Redding Type S FL die on Alpha, Norma, Tubb brass. I never had a problem with any of the brass.
    I was one of the testers for Alpha on the 6xc brass and can attest that I put 13 firings on the same 6 pieces of Alpha Brass with a basic Redding die and never had bolt clicking issues. The primer pockets were still tighter than new Norma brass.

    Btw..use whatever bullet you.want. I use 107smk and hybrids all the time

    Sounds good. Thanks! I have a pile of 105 hybrids so I would definitely try to get those to shoot.

    I have the same thing as tbeasley has, but a .105FB. I shoot Alphas brass with no issues, great stuff.

    Robert Whitley has the answer to your questions on his website 6mmar.com.
    Click the tab at the top of his page about the 6xc.

    Thanks.... found it after I posted the question here. I got a couple of his reamer prints from JGS that helped as well.

    FYI.
    JGS has never made a reamer for me... Dave Manson has my reamer specs and will freely share them.
    I use a .278" neck / .160 freebore/1 1/2 lead -- for DTAC 115's
    Base of the case is .4705"

    Our 6XC die set is designed to small base and full length resize.

    Wasn’t Hugh Henriksen involved with you when you first designed your 6XC?

    absolutely -- Hugh is a fantastic reamer maker.. don't get in a rush.

    By the way -- JGS makes great reamers also they just haven't made any 6XC reamers for me. Had some JGS reamers in other calibers.
