Hammer bullets G1 B.C.?

[antleredacres]

I'm very interested in trying out a couple Hammer bullets. Specifically .284 120 HH and .264 124gr. HH. They are listed with the G7 BC's. I'm more familiar with using G1 BC's. .284 is listed at G7 .193 and .264 is listed at .245. What would be the approximate G1 BC for each bullet? Thanks

Take a ballistics calculator and calculate the trajectory with the g7 number. Then switch to g1 and play with the bc number until it matches the trajectory when you ran the g7 number

Here is a link to a calculator for the estimated conversion.

im running the 124HH in a 26 nosler at 3525 fps, custom turret setup for g1 .475 bc its a 1000 yd hunting rifle.

If you double the g7 it will be very close to the g1.

The 124 HH is stupid.....accurate.
My daughter shoots this bullet in her 6.5SLR. I shoot the 131 in my 6.5SS, but am currently testing the 129 Absolute Hammer too.
Plus, the 101 HH in my 6CM, 121 HH in my 25SST, 177 HH in my 28 Nosler.....
