Well, I finally got to test the GS Custom 120 HVs out of my .284 STAK (300 Dakota, necked down & improved, similar to Rolands 7mmRHB). At 100 yards my groups were consistent at 3/8" which was not quite as tight as the 140 or 160 Accubonds, BUT last night I shot the 120s at 613 yrds with my 3 shot group being 1 1/8" center to center. The math says that's well under 1/4" MOA. The best I ever shot with the accubonds was 6 1/5" at 650 yrds. Needless to say we were quite impressed with these GS Bullets. When I got home I ordered another 100 bullets and will be testing them at 800-900 yrds. I wish they weren't so expensive ($140.00 airmail shipping included) but I can't wait to go shoot them again. I would send a photo of the group if I knew how.
Load data is as follows:
78 grains of RL 22
3730 fps.
27.5" shillen 1-9" twist contour #5
Ziess 4.5-14X50 scope
I'll let you know how the next tests go. Will be trying to determine BC but right now it appears it's around .4
Good shooting,
Steve
