unless you have pistol gas barrel - or a bolt/single shot - save the lil gun for the supers. with a carbine gas setup - at least unsuppressed - lil gun wont cycle under 208 amax subsonic. it just doesnt produce enough gas volume and it'll short stroke on you. Even with a pistol gas it may not cycle properly, i cant tell you for sure as i switched powders before i built my 9" ar pistol or had my suppressor.
for the least drama you can find.... stick with one of the powders known to work well in the subsonic realm - 1680 and DO63 (shooters world blackout powder) both really shine there. From what i read the DO63 burns quite a bit cleaner than 1680 does. 4227 seems to work well. The good part is subs are really efficient on powder so a pound will usually get ya around 625-650 rounds.
you can use 1680 data to work your loads for the DO63/Shooters world blackout - but its just a bit faster. I had to drop my 208 amax load down by 0.3 grains to match the velocity of 1680 for subs - this was for both my 9" & 16" barrels.
for the varmageddons - warm them up a bit and they should do pretty well for ya under lil gun. I ran them right up to max charge and there was no pressure signs for me and they shot quite well there. Varmageddon's make a great deer hunting bullet and at blackout speeds expand like a typical bonded hunting bullet would out of a more traditional deer caliber like 30-30, 308, etc... I'm currently hunting with the 125 SST, but my 2nd choice would be a tie between the 110 varmageddon and the 110 vmax.
