6.5 grendel mp501

[supercorndogs]

Anyone using it with a 123g bullet. I worked from 28-31.9. The first load I tried was 29.2 but it was only 2350. So I worked 30-30.8 then 31-31.9. I decided to try anther load 31.3 which is about 2450 in my 18" barrel. 31.9 was 2500. Anyone else worked with mp501 in the grendel? I figured I would run this 50 peices of brass a couple time on 31.3 and see how it holds up. I was hoping to get in the 2520-2550 range.

No sir. But I use 123's with only CFE and XBR powder

I got about 2450 with 8208 but the case heads look better with this powder even at 2500.

The primers still seat snugly in the 31.9 cases. All 50 peices are sized tumbling waiting for prep. Maybe I will work up to 32.5 or 33 and see where I end up. Velocity vs charge weight was pretty close to book numbers for LVR in my 6 arc. I am waiting for PV to ship my LVR.
