After having read various reviews of Lil Gun (more unfavorable than favorable), and several loading manuals, I was a bit hesitant to use the stuff, especially as a reduced load in my .30-06. According to several burn rate charts (Hand Loader #317, Lyman's latest manual), Lil Gun is slightly slower than #2400 and the equal of SR-4759. That makes it a viable propellant for CB loads. Today I tested that hypothesis and chronographed the results, which I confess surprised me a bit. Is it accurate? You bet; actually as accurate as the 12.5gr. charge of Unique I use with gc'd CB's in my .30-06. However, 18.5gr. -> only 1156 fps +- 17 fps with a CBE 195gr. Loverin (gc'd). I'd like to bump up the velocity a bit, say to 1,400 fps with something like 175gr. - 185gr. CB's, so I am thinking 20.5gr. - 21.5gr. max. may be the answer. Btw, the case necks were hardly sooty at all and the primers showed no signs of pressure.
