Dave;
I tried the 130 berger and jlk, not able to push them fast enough to make use of the bc. The higher bc of the big pills is great except the Grendel can not push them fast enough to stay in the higher bc. Here is some quick info from us shooting this last sunday at 1084 yards, 9500DA, 8 degree slope. Grendel with 130 JLK at 2600 (which is at max pressure with cfe 223) took 10.2 mils elevation and 1.7 mils for windage. The 108 at 2780 took 10.2 mils elevation and 1.8 mils of windage. The windage is for a 10 mph from the 3 o clock position. Huge differences? The .1 mils difference at 1084 in wind is 4"m yep 4 inches. Now lets look at 600 yards with the 130 it takes 3.9 mils for elevation and .7 mils for wind. The 108 takes 3.8 mils for elevation and .7 mils for wind. Now lets hit 300 with the 130, 1.2 mils and .3 for wind. The 108 is 1.0 mils for elevation and .3 for the wind. Now the 130 data is for 2600 fps which is not achievable in the summer (in my opinion) versus 8208 which is quite a bit more temperature stabile and you can have one load for all year. My load is not at max pressure but you can not fit anymore powder in the case, I believe the guys with 24" barrels will get another 25 fps over my 20" plus can. Good luck and let us know how it turns out.
