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.
