I ran Lil Gun for my Marlin loads, 15.5 or 16 - not sure off memory, but that sounds right, 158 JSP RP. 2050 on Chrony.
On that Moose, was that a handgun kill - or finishing shot? Just wondering, congrats! 1150 - 1200 will do alot with a good 158 or 180 class, assuming good construction.
When I was loading for a GP100 4" and 686 4", I ran alot of 110/296, extraction was often difficult in the Ruger, not sure if the cylinders were rougher, but I had them quite hot. It does seem like I ran some top end 2400 as well. Never had any issues with the 686, or other K-frame guns with extraction, but I may have been a bit 'ambitious' when I was loading the GP100. A gun I always wished Ruger would have made in 41 Rem mag.
