lil gun and 300BLK

skizzums · July 2, 2014, 03:02 PM

hey guys, need a little advice here on 300 blackout load

picked up some 155gr amax in hopes to use this lil gun i bought since it wont cycle with my subsonics, having a tough time finding a reliable starting point

looks like i should start a little over 15gr but just want someone with some experience with 150ish grain bullets and lil gun, and also what is the safe max load

8,5in BBl 1/8 twist

thanks!!

Hodgdon's max listed load for lil'gun and 150gr Hornadys is 15.2gr

Based on that, your max should be right around 15.0.

Hornady's reloading manual list 11.8gr. minimal and 17.0gr. max with the 155 A-max

awesome guys, thanks alot. ill start about 14 and half and work up from there. i know better than to go too low on the spectrum with the semi auto's, they are so finicky

As a point of information, QuickLoad agrees with Hornady, max at 17.0gr. I don't know if I'd go down to 11.8gr though, that's barely 60% case fill.

QuickLoad says 1736fps from 17.0gr in an 8.5" barrel.

Very efficient load. Basically the best powder you could use.

I settled on 15.8 gr, got to to shoot yesterday, pretty sweet groups at a hillbilly 30 yds. That thing kicks like a mule compared to the sub-sonics. But everything cycled well and bolt lockback. Thanks.
