I might have some small group pictures somewhere, but here's a 20 shot group from a 300 yard reduced slow fire prone course I shot with my grendel this weekend. Wind was 10-15 from 10 o'clock. The grendel can still keep up with the wildcats.
    I would say with a Grendel 2450 with the 130s is good anything 2500 and up will be tearing up your brass. Maybe higher with a bolt gun.

    would like to see quickload data on this.

      My brass is doing fine. I am using leverevolution and cci 450 primers in a 28 inch barrel.

            Now THAT I'd a sweet looking piece! I'm woking on a LVR load for my 16" with 123 ELD... 31.6gr makes me giggle, but I'm nervous about the pressure come summer time.. What kind of temp flux have ypu noticed with LVR?

              I am seeing some temp sensitivity. I did some load development at 50F and there was a really nice node at 30.5gr of LVR. I did some more testing at 75F and the node moved to 30.4gr. I decided to go with 30.3 gr. That's on the low edge of the accuracy node at 75F and gives me some breathing room. I also keep my loads out of the sun until I am ready to use them.

              Sorry about hijacking this thread.

                I couldn't get the velocity nor accuracy with 8208. Switched to Varget and achieved excellent accuracy and 2750 fps with Sierra 107's. This is with a 20" barrel.

                  LoL that is my load too! 30.3grs of Leverevolution over a 130gr Hornady ELD Match. I get 2560fps out of my 24in AR. Where I live it matches the BDC reticle of a Bushnell 4.5-18 223 Dropzone scope out to 600 yds, or Strelok Pro said so at least.

                  It's nice that our node is in the same spot, it may be there for everyone then. Do you know anyone else who does 30.3grs of LVR with a130gr pill?

                    My load is 30.6. I haven't played with the 130 ELDM or Berger in a couple of years. I'll load up some at 30.3 and revisit it next week. I'm shooting a 22" barrel so perhaps my node is different.

                      Around 30.3 of Leverevolution may be one of them sweet spots that shoots great from most guns.
