Range Report Hornady 178 BTHP

[223ai]

All -

Hornady shows a G1 of .530, and I tend to think that it's a bit optimistic. Does anyone have realistic G1 and G7 values for this bullet?

Thanks,
JP

Information from Bryan Litz book Applied Ballistics for long range shooting. A must have book.

I used .530 in JBM and shot it out to 800 yards at the Oregon Sniper Challenge last year and it was right on with that number.

I used .530 out to 620 yards running at 2550fps and its spot on.

Thanks Gents. Those Litz numbers jive well with what Lowlight doped out on the Superformance ammo testing a year or so ago. Sounds like a good place to start.

Best,
