GS Custom 120HV Bullets tested at over 600 yrds

Got out again to shoot further and was only able to go to 745 yards. I was using an inferior rest sytem compared to last outing but the best 3 shot group was 4 1/2". The other group was 1/2" bigger. These bullets seem to be very consistent and I believe with a steadier rest I can cut an inch or so off the small group. The new shipment of bullets only took three weeks to get here. Can't wait to use them on deer this year.

Best, Steve

if your load is shooting 1/4 moa at 600 yards, the BC means nothing!

Dave, if I understand what you mean I totally agree. But, for curiosity sake, I believe it's a bit over .4. I won't be taking shots on game at over 600 yards most likely, depending on the available rest, so what difference does the BC make??? Is that what you mean?? Steve

Hi, regarding the GS HV bullets: I spoke to someone at the manufacturing plant (I forgot his name, it was a while ago) and when I asked about the BC of the 7mm 130 gr HV bullet, he said that one should use G5 tables to get good results from a ballistcs calculator. He calculated the BC for that bullet to be approx. .57 @3400 fps

I have tested the 160 HV and 173 HV bullets for BC. They are very accurate. However, they fly like bricks. The BCs I got when shooting over two chronographs indicated the 173 HVs were in the area of .341 G1. Additionally, they had way more drop at 400 yards when sighted at 100 yards than a 150gr Nolser Ballistic tip. If they would stick a polymer tip on the bullet, then they would be hard to beat. I made up some with tips but scrapped the plan since they were so expensive.

The Lost river bullets would fly but not expand reliably. If you could take the tips from the lost river bullets and apply to the GS Custom bullets, then you would have a winner. Until someone with reliable supplies of aero-slick expandable bullets beats the accubonds, I will stick with them.

I have the long range shooting sticks, I am just waiting on some good bullets that can be had relatively easy. The Canadian bullet maker won't respond to my emails for orders.
