Here you go

Gun info.
SSK upper
16.25" 1:8 twist
pistol gas port
both loads below were shot before suppressor arrived so velocity would probably have been slightly higher w/supp.
pay particular attention to the 2 different overall cartridge lengths and the affect it had on velocity!
220 SMK / 220 SMK
9 grn Lil' Gun / 9.5 grn Lil' Gun
Rem 7 1/2 /Rem 7 1/2
OAL 2.100" /OAL 2.225"
6 shots / 5 shots
Avg 1154 / Avg 1134
ES 87 / ES 65
SD 31 / SD 25
7" group verticle dispersion
1.25" horizontal dispersion
The 9 grn load was shot 5/26/11 over an Ohler 35P Temp 65 deg.,35% RH, at 5100' elv.
Can't seem to find the target for the 9.5 grn load.
Hope this helps
