Lil'gun is a good powder, but onley for the pistol. i had a friend run some Quick load numbers for me using Lil'Gun with a 440gr lee WFNGC and the data showed that the powder was completley burned with in a 7" barrel. so uaing it in a rifle does not gain you anything as the barrel length just ends up slowing down the boolit as then is no more powder to burn. i had him run some tests on rifle powders and Quick loads showed W-296 to be the best at 99.8% powder burn in a 22" barrel. the max load data we came up with was an OAL of 2.130" using a 440gr lee WFNGC cast boolit backed by 41.8gr of W-296 giving me 2005fps at sealevel. quick loads says this load will onley produce 59,000psi but of course this needs to be worked up carfuly so one does not die in a blaze of glory. its funny as i just came here to post about rifle powder and found this thread. peopl say h100 is the same as W-296 but acording to quick loads you will get 50fps less using H110. any one use W-296 behind the 440gr?
I've used QuickLoad v3.4 and now v3.6 for several years, it works great with bottlenecked cartridge data, but it doesn't work very well with straight walled cartridges, just try duplicating the data of any published straight wall data!!
Lil'gun works great in my 500S&W H&R using the 350gr Hornady(2150fps), 385gr Rem(2100fps), 440gr CP(1950fps) and the 700gr RR(1435fps). I use it exclusively in all my pistol chambered H&R rifles except the 357 Maxi, it provides excellent velocity, not to say there aren't some rifle powders that won't work tho, there just isn't any data available for slower burning powders, so you're on your own.
