JB1000 - 223ai range report?

I should get my rifle this week. I used the same chamber specs you used,throated for the75 Amax).

Have you done a range report yet and I just missed it? Would love to hear what powder you are using and your results.

thanks,

Keith
 
Keith - here was my reply from SH:

Keith - ended up at 25.5 Benchmark with a 75amax for about 2975fps, 205M primer. Haven't had time to play further

2.5" OAL puts the amax 20thou in...so the reamer is a little off of what I spec'd, but it works.

Bout 33MOA to 1000yds. Banged a little steel but haven't had a chance to test it further.

R15 is giving me too much temp. stability issues at this point,30fps change for 20deg. in my 6.5x47) so I went with BM in the AI. H4895 might be the perfect powder for this case.

R15 gets the velocity, but the temp. sens. that my Ohler 35 has shown me worries me a bit for an all-around field load.

Just haven't had the time to really wring it out as it is 1K BR season and I have other things more pressing.

Send me an email though, and I'll get you the velocity results from some other powders. Tested a few for velocity and pressure, but stuck with BM for development.
