TAC with cast?

[cs86]

I was loading some jacketed .223 rounds yesterday using Ramshot TAC powder. It made me wonder if it could be used for cast bullets. Primarily .223 or possibly 300 blackout? I've seen no published data out there, but wondered if it would be an alright candidate for the 300 blackout? Anyone ever seen any data on it for cast or try using it? I'd be willing to try but have no starting point to try it out.

TAC is too slow for 300blackout. It is excellent in .223, 30-30 and .308. It's in the same area on burn chart as Varget and h4895, 2 of my other favorite powders. I haven't downloaded it though so I can't speak to its ability there.

it'll work in the 223 with cast.
the load will be the easy part.
getting everything else to co-operate at 2800 fps will take some work.
