took it to the Hernando Sportsmans Club range Saturday. With my 158 grain LSWC and 6 grains of Unique powder, it was delivering one inch groups, or less, but a little high and to the right, at 10 yards. Snappy round.
I also like 6 grains of Unique with cast bullets in a Model 10. My favorite bullet is the LBT 160 grain WFN. I think it was MontanaMarine who ran the numbers through his Quickload software and it said the load was about 26,000 CUP,...which is about right where a modern Model 10 load needs to be, in my opinion.
I've also been working up some loads with the same bullet using AA#5 just because it meters very well.
AA#5 is a bit faster than Unique so I'm looking for the place that puts it where the 6 grains of Unique is.
