sititunga,
Have you looked at some of the slower powders for your bullet and barrel length? It seems that I am getting about as much velocity as I can on the edge where brass life suffers more with that load. If you even out the pressure curve with the available barrel length you have, it should be easier on your brass, bolt, and throat. I'm pretty sure I felt some loose primer pockets after that batch, and that was probably only the 3rd loading of that brass when I loaded last.
There was a ton more information about this on the forum before it was destroyed by someone. It had each bullet categorized in the reloading section in a very helpful manner, with lots of real-world experience from forum members trying several different powders, COAL's, barrels, etc. It would have made a great source for a reloading book specifically for the Grendel.
When I did my initial load development, using the same powders, brass, and bullets as AA, it seemed to work out that I had about 18 fps loss in velocity per inch of barrel length with the Grendel, but I've heard others say it is more like 20-28???
I know that my 30.0, 30.5, and 31.0gr loads with the 100gr NBT's felt nothing like the 120gr and 123gr loads...the recoil was almost non-existent. I'm kinda excited to see what happens with the Elite Ammunition 98gr solids. They will be very forgiving with pressures as there is much less bearing surface with the driving bands. If I can get them to go 2750 fps, they should extend my effective range to maybe 700.
