GS Custom 120HV Bullets tested at over 600 yrds

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

Stevet, Wow that's sounds like an impressive load. What is the BC of these bullets. 120grn Bullets at 3750fps, that is an awesome varmint combo.

Wildcat, we are still trying to figure out true BC. We're using the xball program in unison with shooting different distances to figure it out. Right now it appears to be around .4. GS Bullets are small in weight and BC by comparison to Berger Bullets or Wildcat Bullets, but I like the solid copper bullets for hunting, and if they fly that well......then it's a no brainer for me. Definitely a different philosophy than the big, long, high BC bullet. I'll keep you informed on the testing.

Best, Steve

Are you located in the US? Who did you order from and how long did delivery take? Thanks.

I ordered them on their website, and yes I'm from Utah, U.S.A. Gina, who I believe is the owner of the company that her father founded, was very good at coresponding with me via email about how long it would take for me to receive them. It took them (GS Custom) about 10 days to manufacture the bullets (as they didn't have them in stock) and about three weeks to get them to me via airmail from South Africa. So, total time was a bit over a month from order to delivery. She emailed me after my recent order and said it would only be a couple of days to manufacture the bullets so I expect them under a month. Personally, I wouldn't have them sent any other way than airmail. They seem very busy trying to keep up on orders and I don't know if they regularly have the 120 HVs in stock. I've got enough bullets to get me through the delivery of the next order so no worries. If you can afford them you should give them a try. I'm confident even at this early stage of testing they will be very accurate out of most rifles. 800-900 yards next week and I'm really hoping for the same experience. Remember they have requirements for specific barrel twists for each bullet. Mine is a 1 in 9" and I believe 1 in 9.5" is considered the slowest for those bullets.

Best, Steve

Did you determine the BC yet? I use their 330 gr GS from my 416 WBY at 3100 fps and it is accurate.
