Seems like the powder for big and heavy.

The_Shadow · November 16 2014 03:54:38 PM MST

Yep, Lil'Gun has a good velocity to pressure for them. ${$default_wink_smiley}$

Intercooler · January 18 2015 04:39:41 AM MST

No wonder the Georgia Arms felt like firing a Cannon! Given it is also Lil'Gun, it would be best to not shoot a ton of these?

The_Shadow · January 18 2015 10:14:29 AM MST

Yea I found that charge to be higher than Hodgdon's data and checked against Alliant MP-300.
They are showing data for 10" barrels
Hodgdon shows Lil'gun, 18.0 @ 1577 fps 25,800 CUP (lower pressure than the other powder like H-110 and 296 40,700CUP)
Alliant MP-300 18.6 @1690 fps

Intercooler · January 18 2015 01:30:32 PM MST

I looked over the .44 Magnum sheet and some of those don't have that amount of Lil'Gun ${$default_shocked_smiley}$
