Just a bit of experience - but with J-bullets in .300 BLK. I had best results with H110 at just
under 10 gr. 10 gr popped supersonic too often. 1680 didn't impress at all after being told
"you HAVE TO use 1680 or the AR won't run". Mine runs perfectly with H110, or 2400.
1680 seemed to give trouble running if lowered to subsonic. Go figure.
Since this cartridge seems to have a LOT in common with the .30 Carbine, it would seem
that a powder created for .30 Carbine (H110) should be perfect. IME, with 220 Sierra
JHPs, it is.
Have not wanted to crud up my non-disassembleable can with normal lubes, so staying with
Jbullets so far. Considering commercial powder coated cast as an experiment - not really interested
in getting into P-coating.
