I have been using them out of a 7mm Sherman MAX and a 7 PRC. The MAX, I just started shooting so I havnt verified with it yet. The 7 PRC I have verified out to 1000 yards and I have the 170 HHT at .260 G7.
Rifle:
Hells canyon Armory build
Action: Tikka T3x
Barrel: HCA carbon barrel 24" 1:8 twist
170 Gr HHT at 3050 fps avg. measured with a garmin chrono.
looking at my notes, When I verified it was 48 degrees outside. I started at 1000 yards on a 24"x24" plate. I put in the estimated BC (.287) from the hammer website and I hit low. So I just kept adjusting the BC until I got the elevation centered on my 10" bullseye. That was at .260 G7 BC. I then went to 800 yards, 600 yards and 400 yards and verified just to make sure and it was good.
My 14 year old son shot a cow elk at 820 yards with this setup and it worked great.
