A couple of years back, I was gifted with a lb. of 'Tin Star' powder but haven't used it due to the lack of published data.
The current issue of 'Handloader' magazine has an article on it with tested loads in all the CAS pistol calibres and the 30-30 and 45-70.
It's slower burning than 'Trail Boss', looks different (cubes as opposed to flat donuts) and does not come with the "up to the base of the bullet without compression" load density caveat. Loads are a few grs. more than with Trail Boss, so don't extrapolate the data!
It's said to be clean burning and the heaviest loads gave the most consistency with respect to extreme spreads and group sizes. Oddly, with the same 5 gr. charge, Vihtavuori recommends the use of small Rifle primers in the .357, but not with the .44 magnum even though the load is heavier than the .44 Spl. load. Go figure .....
I just hope it doesn't have the strong chemical smell that Trail Boss creates.
