My goto load for .357 is Red Dot. 5g of Red Dot under 158g SWC bullet chrono's at 1019fps out of 6 1/2" barrel.
I've used it for .357, .44Spec, .44Mag, .45 Colt, and .45 ACP. Found accurate loads in all these calibers. Not for 'magnum' loads but good general purpose loads ... ie. 'fun' loads. Excellent powder! ... and I don't find any 'filthier' than any other powder I've used....
4.5g red dot 200g swc 45acp is a very accurrate for me.
+1 . I like that load too. Note I don't have a semi-auto, but shoot them from my .45 Convertibles.... However, I have settled on 5.0g of Bullseye under 200g TC bullet as my goto load for this bullet .... for no other reason than 'just because'
. Both shoot very well.
