    First 6.5 Grendel

    This is the first barrel on my Grendel reamer. After some research as to why it won't chamber AA 123 ammo I have come to the conclusion I should have bought the Grendel reamer with the parralell throat. Just going to have to use the throat reamer for now. image.jpeg

    Fwiw, if it has a parallel throat it's not a 6.5 Grendel.

    Care to share why your research led you to your conclusion?

    What reamer did you use?

      I used the standard Saami reamer. I found several things talking about the standard reamer and the parallel throat reamer. I tried calling AA to no avail. I checked the length of some hornady black 123 gr ammo vs AA 123 gr scenar. Base to ogive was substantially longer. Don't have numbers in front of me but it was in the neighborhood of .040. Any info that could be shared would be great. Thanks

        To be clear, I'm no machinist. I'm mainly bumping the thread hoping some of our experts chime in.

        I didn't word word my question properly. What I should have asked was; who made your reamer?

        There have been issues with certain reamers that are called 6.5 Grendel but technically are not.

              Ben you are not the first person who has had an issue after using the ptg reamer. From what I've read here the one to use is Manson.

                I use the Manson SAAMI reamer that is verified with optical comparator before it's allowed out the door. There are no issues with it, and I've fixed other chambers with it before that had really short throats.

                I personally refuse to let a smith use PTG reamers even when I'm doing a .223 Wylde chamber after my experiences with incorrect, short throats that would blow primers with .223 ammunition even. I've also heard complaints from manufacturers about the reamers they thought they were getting, then got another. Companies don't want to talk about it because they rely on certain tool makers for many of their other critical tooling like bore cutters, buttons, etc., so it's a touchy subject.

                I was going to do a .338 Federal on a GII a few years ago as an experimental test bed for some other projects, and the smith said he had a PTG reamer he would use. I said no way for my project, and he didn't want to order another, so I never moved forward with it.

                Looks like you didn't get a SAAMI spec reamer.

                  I actually found several issues and have it chambering like a champ. I did take the throat out but still had some issues. Ill probably take it to the range this weekend.
