Just currious if that BC worked past 1000 yards too?

Thanks

Jeff

Broz,

I have only shot them out to 800 yds. Elevation 1500 ft.

I was running them out of a 338-378 weatherby with retumbo @ 2988fps. they shot pretty nice haven't messed with them since though.

I havent been on here lately, just recently learned about the 300gr AB. This thread seems to have the most info on it. Anybody else had any time with these bullets and maybe some more info, as far as BC goes (G7 value would be nice), terminal performance, or any info with a 338LM?

One a side note, getting okish results with berger 300OTM. Mostly just over 1MOA

I have taken 3 crop damage deer with the 300 gr AB out of a 338 RUM at 2680 fps.
86 yds exit

200 yds entrance and exit

439 yds entrance and exit

Thanks JD, is the .720 BC still working for you? Anybody know if Bryan Litz has tested the G7? I looked throught the Shooter app, and it is not listed.

I am using G7 drag with a .375 BC. Its working well for me out to 800 yds.

From Nosler, the BC will be .720.

Yeah, and Nosler has never been known to exaggerate a BC. Actually we've measured lots of BCs and Nosler's numbers are often exaggerated compared with our measurements.

See:

http://arxiv.org/ftp/arxiv/papers/0705/0705.0389.pdf

and

I also seem to recall that most of Nosler's BCs are more optimistic than the measurements reported in the Litz book. I would not believe a Nosler BC until confirmed by an independent measurement using either a velocity loss or time of flight measurement.
