I recently aquired a Ruger M77/357. I've tried several loads in it and it's marvelously accurate with 17.4gr of Lil'Gun under a Remington 158gr JSP. It chrono's to 2,020fps avg. (10 shots) and has given some 1.5" 3-shot groups at 100yds.
I've tried #2400 under the 200gr FN (mine casts to 215gr) for ~1,350fps (9.8gr). It grouped acceptably but at max load won't quite get the speed I'm looking for. (1,500fps if possible).
Obviously, I'd like to try the Lil'Gun and want to know if others have tried this powder with this or similar boolit.
Hod. gives data for a 180gr Jacketed as their heaviest listing (15gr).
As title states; I'd like to hear others experience and suggestions to include H110/Win296 or H4227.
btw; the 158gr Lee TL-SWC shot suprising good over 6.0gr of Unique for 1,385fps... Shot ~2" at 50yds. Suprised me!
