Trail Boss in .308 Winchester

[Shuz]

Anybody have any accurate cast boolit loads with Trail Boss powder in the. 308 Winchester that they would like to share? Boolits in the nominal 165 to 180g range.

I tried 12g of Trail Boss behind a NOE 311 165 at a CBA match on Saturday and the results were dismal.
I would shoot a couple of nines or even a ten and then a shot out in the 3 ring! My total score was only 147 (out of 200) and I normally shoot between 165 and 180 with this rifle which is a Savage mdl 11.

i would only use trail boss for subsonic loads in 308, they would be in the 9.0-9.5 range, i think. Anything above that I would use a different powder as trailboss is a fast, but bulky powder. With cast, a slower powder would like improve groups in the supersonic range. Trailboss peaks out in pressure fairly quick.

I don't have the charge handy at the moment, but I have used Trail Boss for 200-220 grain sub-sonic rounds. They have the trajectory of a Red Ryder bb gun, but are accurate. With the bullet weights you've listed, the round should shoot a tad flatter. It's definitely worth a try.
