Lil'Gun is used by some of the 300 Blackout folks. That's why I happened to have some on hand, from loading 300BO ammo. I guess it could be called a "Magnum Pistol Powder". The burn rate for Lil'Gun (62) is right there around H110 (63), IMR4227 (65) or even SR4759 (67) powders.
I used QuickLoad program to work up most loading data. I'll double check with several of the loading manuals I've got to make sure I've not got something way out of line. I was looking for a load to give something in the 1400 to 1500 fps range, but with low pressure curve and still provide most of the powder burnt. If I'm loading a load for hunting or long range shooting then I'll load more toward the max allowed for the rifle I'm shooting.
I don't like TrailBoss powders - while it's a bulky powder for better case fill it's a really fast powder with a burn rate of 19, between Bullseye (13) and Unique (31). All those powders are fast giving a high peak pressure for the amount of bullet velocity.
Yea, I know, sometimes I get pretty wordy when asked a simple question. I've been told I'm a person if you ask "What time is it", you'll have to listen to a history of time and watchmaking before you finally get the time {g}
