I am looking for some real life numbers from the 6.5 Grendel. If it all possible, 24" barrel and any of the following 120 SMK, 142 SMK and 130 Norma Diamond. If known, the peak chamber pressure would be a welcome item too.

I tried mulling through the 6.5 FAQ but there is "too much of a good thing". I did see the 120 SMK gel test, 24", 2660 fps at 49,800 psi.

Thanks!

Only data I have is from me loading the 120grSMK on top of 27gr of IMR4320 getting a velocity of around 2200fps. I am NOT using an extremely efficient powder, but I AM getting 1" groups at 150yds, so I am happy with that part. I just happen to have a bunch of IMR4320 kicking around, so I use it when I can to avoid having to go blow more money on another powder type. Already had to do that with the .50Beo as I had NOTHING that would work for that! Oh, I have a 22" barrel with Miculek comp on it. AND a curly maple ff tube too!!
