Just picked up this gun as a plinker, and maybe a deer gun for Pa.
I've been trying out some loads using 158gr cast SWC, and 158gr Sierra JSP, and the Sierra 170gr JHC.
Looking through the loading manual for LIL'GUN info used with the 158gr jacketed, it seems as though they are getting pretty good speed (1577fps W/10"bbl), with comparable very low pressure (25800 CUP) compared to a max. load of H4227 (1520FPS @ 42600 CUP), or a max load of H110 (1591fps @ 40,700 CUP).
The load I tried (18gr LIL'GUN W/ 158gr) seemed to shoot the best (accuracy wise) out of all the loads I tried using Unique, Bluedot, and LIL'GUN with 158gr cast, and 158 & 170 Jacketed. With iron sights, I was getting just over 1" @ 50 yds.
Now my question is, is anyone else using LIL'GUN in their levergun loads? The speeds in the book are for 10" barrels, has anyone cronographed their LIL'GUN loads to see what speeds they are getting out of a rifle?
