9mm Major with HS6

[docscoutjr]

7.7g of HS6, true bore comp.

Mixed brass, ambient temp about 9C.

1.17oal, 124g FMJ

Atl 970m

Average of 10 = 1355!!!

This seems a tad high?

Chrono is good (tested with known rounds), metering problems on the 550 possible, but not likely, only thing might be the mixed brass? That or, just the thin cold Canadian air?

That sounds decent. I haven't used 124's for a while but I use about 9.1 for a 115 grain bullet.

Heck yea, seems that at least 8 is needed from what I have seen here.

Though 9.1 at sea level with 115's isn't too far off.

8.3 at 1.175 OAL with a 124, gave me 172 PF

8.5 at 1.165 with a MG 124 CMJ in a 5" TruBor with 2 popple holes gives me about 170-171 PF.

At 1355, that should give you only 168, which is a little low for USPSA. I am assuming you are going by the 160 IPSC PF? If so, then yes, that would be a little high for you but not bad at all.

Thanks, yes IPSC.

When I shot hs6 in 9 major I loved it. Its been awhile but I used 124 bullet and 7.8 thru a truebore and was making major.
