Range Report BC on 308 Corbon 175gr Ammo/Ballistic FTE

[amcwhorter]

Right now I'm guessing the bullet used is a SMK BTHP and the BC is .496. Does anyone know for sure? **Found the answer!***

Using the B-FTE also has drag options G1 through G8. According to what I've read and assuming the bullet is a BTHP, I should be utilizing G5. Wrong or right? If wrong, please explain or point me in the direction.

Thanks
Mac

Okay while searching further my assumption on the bullet being a SMK BTHP is correct.

Still looking for any answers to the rest on drag options.

Thanks

I use the G7 with this program, for 175 SMK BTHP the G7 AVG is .242 for my set up, the G7 BC is much better for LR shots over 500M.

I just setup my B-FTE with 3 different custom load saves. Everything i'm reading is coming down to going out and trying it. So I loaded G1,G5,G7. Every one of them is giving me different results.

This is coming out of a 22" barrel pushing 2630fps avg from 10 shots.

Thanks Skinney for the info
