I have shot lots of that very same load, though any more I seldom use the 357-446. 25 years ago I got a 4 cavity out of the Used bin at Matthews and Sons and after replacing the strpped lock screw on the Sprue plat bolt, I proceeded to cast and shoot buckets full. It makes a fine plinker, but is not as accurate as the wadcutters, or for that matter the 358-311 round nose.
These days I cast lighter boolits for plinking, both to save lead, and to limit recoil for the grand kids.

5.0 Unique and the 358477 or any 150-160 gr boolit is sort of a standard 38 load, for me at least.

Unique at 5 grs under 150-160 gr cast bullet is a max standard pressure(not +P) .38 spl load per the Lyman cast bullet handbook. IMO should be fine in any model 10 you want to shoot it in.

I think the powder is fine if the bullet is not undersized.
