      Maybe my google Fu is weak .. I did a search and saw no posting on results for this mold
      Anyone with results on 266-125 6.5 grendel mold
      what barrel length, twist and powder load and what accuracy results did you get

      Thanks

        I bought one over a year ago but still haven’t taken the time to cast with it and do any load development with it yet.  It’s on the list of things to do, but somehow it keeps getting pushed to the back burner.

          I UNDERSTAND THAT ..I am just getting back to this myself ..
          pig hunting has got me thinking if I could get that bullet to shoot in the 2200FPS range (powdercoated of course) and no worse than 1 MOA I could drop these Hornady SST’s and be nearly 100% cast shooter

            How hard or what alloy are you going to cast them out of?  Also gas check or plain base?  Oh and AR or bolt gun?

              was thinking 98/2 alloy gas checked and powdercoated
              I would be shooting a AA 18″ AR  .. it shoots 3/8-1/2″ 100 yd groups now if I do my part right and a quality scope
              its wearing a Pulsar XP50 trail Thermal right now

                Well, now that sounds like a lot of fun!  Need those hogs to invade Utah…

                  according to this map they are already .. may be just in certain areas

                    I’ve not heard of them here.  With all the shooters here in Utah, I think hogs wouldn’t be able to survive.

                      3 years ago we started to have a couple sightings now its a large population and seems to double every 9-12 months
                      Hogs have no natural predators in this part of the country .. They breed fast and often

                        I have been shooting it in a 15″ contender in our monthly IHMSA matches. I have been playing with strange loads, like Hybrid 100V, and IMR 4064, mostly because I have quite a bit of it. I have been working for 2000 fps and it has been shooting well for me. I have be using heat treated COWW and Lars new blue lube with good success. If I do my part I can shoot moa with them.

                              You’re going for a 98% lead and 2% tin bullet? Or were you going to use antimony? I would think 2% tin would be too soft to push to 2200 fps reliably. When I go that fast I use Lyman #2 or something with a higher percentage of antimony. I have a recipe that harder than #2 but not quite Linotype.
                            Anyway, I’ve got a 1-7 16″ AR barrel that I had to tweak with a chamber reamer so that the bolt closes on my 7.62x39mm cases which have been  converted to 6.5 Grendel. From what I’ve read it’s due to the fact that the 7.62 bolt face isn’t deep enough. I tried cutting down the bolt face but it’s just so dang hard I figured it’d be easier to cut the chamber a couple thou. So now I just need to get to the range.
                            I use Quickload to get a starting point. I came up with the following to start

                          IMR 4064, 26.3g, NOE 266-125-GC – 35k psi, 2076fps

                          The thing I liked about this powder (using this bullet) was that you can fill the case and still not over-pressure things. According to Quickload (and it has been a fairly good prognosticator). Here’s the 100% capacity load

                          IMR 4064, 30.12g, NOE 266-125-GC – 46k psi, 2310fps

                          Of course I haven’t tried this yet so I’m going to creep up on that 30.12g load.

                            Alvin I use 98% COWW and 2% HSB  (for the small amount of copper)
                            with this alloy I am able to push a 358 Winchester with a NOE 200gr HP Powdercoated / GC at 2369 FPS  avg and 3/4 MOA
                            That’s mid range jacketed velocity in my load books
                            was able to get a Noe 311 159GR HP to 2000 FPS sub MOA before I quit trying and said that’s good enough
                            hoping I can get the 6.5 to at least 2200 FPS… Know it might require some real work but hey I’m up for it

                              Sounds like you’ve got a good recipe for an alloy if you can push it that fast. What’s HSB, if I may ask?

                                its used as bearing material in industry
                                Mine came for auto plants
