Hi Bullseye,
Lilgun is a flattened ball that's a little bit larger than 296, and it meters nicely.
It seems to have less muzzle flash than H110/296 and works better with the lighter bullets than 296 does.
Accuracy is right on par with the others also.
I have used it in my Hornet, 44 and 454. When shooting lighter cast bullets 215g or 180g jacketed in the 44, H110 gives way too much blast and that's what I use the Lilgun for.
I did some testing in my old hornet bbl and it was quite promising but havent had a chance to try it in this new bbl yet. It's easier to light than the others or at least seems that way. I want to try some in my 4" 357 to try and remedy the "flamethrower" affect.
