The Lil Gun did good at 50 yds, but not as well at 100 yds, I failed to upload the 100 yd groups of Lil Gun. The reason I was wanting to ruduce, is I have seen where people comment that accuracy goes away after about 1800 fps with cast boolits. Yesterday, I loaded up some Lee 312-155. I'm not too sure about my chronograph, the lil gun velocities are not consistant with the 150 gr boolits. Here is the readings I came up with
Lil gun 15 gr 1990 fps
Lil gun 15.5 gr 2050 fps
Lil gun 16 gr 2070 fps
1680 18 gr 1760 fps
1680 19 gr 1810 fps
Reloader 7 17 gr 1675 fps
With the Lil gun, the 15.5 and 16 gr loads were pushing the primers out of the pocket and were flattened out. About half of them popped out.
It's hard to see, but the 17 gr of reloader 7, 4 of the five shots were touching.
