cworks Posted January 3, 2014 Share Posted January 3, 2014 looking for some Suppressed 300 blackout SBR load data 9.5 " barrel AAC SDN-6 Suppressor 220 grain SMK Accurate 5744 powder I have done a little research and most of it is from a 16" barrel but could somebody tell me if 10.5 grains would be a good starting point??

Tom Freeman Posted January 3, 2014 Share Posted January 3, 2014 Are you trying to keep the velocity under 1050 fps? Confirm you have a pistol length gas port. Link to comment Share on other sites More sharing options...
Dawgfish Posted January 3, 2014 Share Posted January 3, 2014 My data starts at 10.7g at 1,081 FPS for 5744 from a 16" barrel and my HVT QD suppressor, so 10.5g ir right in the neighborhood. One of my friends runs a 9.5" barrel and comprable suppressor to yours, but he loads 10.9 grains of AA1680. YMMV Link to comment Share on other sites More sharing options...
cworks Posted January 3, 2014 Author Share Posted January 3, 2014 9.5" Core-15 barrel (Pistol length gas system) I am moving soon and the chrono is packed up, but 10.5 grains of 5744 locked the bolt back and had no malfunctions. I am using a JP Silent Capture Spring as well. Link to comment Share on other sites More sharing options...

chuckd53 Posted January 8, 2014 Share Posted January 8, 2014 Is anyone using Lil'Gun for 300 BLK? Back when I was compiling components, this was the only powder that I could find that had 300 blk. load data. According to the Hodgden web site, the starting load for the 110 gr Hornady V-Max is 18.9 grains, however when I load this amount it practically fills the case to the top, I've been reloading pistol for five or so years, but this is my first attempt at rifle reloads. I know for all of my pistol loads, the powder never comes near the top of the case. Link to comment Share on other sites More sharing options...
cworks Posted January 8, 2014 Author Share Posted January 8, 2014 (edited) I have a pound of Lil' Gun as well but I have never loaded with it. I will say that there are a few guys on the 300blackout forum that use it to make subs. that being said they are pushing a bullet that weighs 100 gr more. I'd start a little low and work up.

bmiller Posted January 8, 2014 Share Posted January 8, 2014 I use lil gun with the Lee 155 grain cast bullet. I like it much better than h110 with that bullet. Link to comment Share on other sites More sharing options...
cworks Posted January 8, 2014 Author Share Posted January 8, 2014 110 GR. HDY V-MAX Hodgdon Lil'Gun .308" 2.040" 18.9GR. 2248 31.000 CUP 20.0 2388 37,600 CUP Looks like 18.9 is about right Link to comment Share on other sites More sharing options...
cworks Posted January 8, 2014 Author Share Posted January 8, 2014 (edited) 8" plate at 25 yards. I'm ready to stretch the legs out but everything is packed up and ready to head back to the lower 48!!!! Edited January 8, 2014 by cworks Link to comment Share on other sites More sharing options...
Dawgfish Posted January 14, 2014 Share Posted January 14, 2014 I couldn't get Lil' gun to function subsonic in my AR with 200GR SMK's. It will fire, but won't lock the bolt back on an empty mag. It will work all day long in a bolt gun. I have 16lbs of it, so it will get used for supersonic loads from 125 grains and up. Link to comment Share on other sites More sharing options...

mic2377 Posted January 16, 2014 Share Posted January 16, 2014 I have used Lil'gun. It is a perfectly acceptable powder - meters well, good accuracy, and very clean. It seems to burn quite "hot" though. I have primarily used it in 110-150 gr loads, but also have experimented with it in subs. It will not run my 16" pistol-gas Noveske reliably while still staying subsonic, although the heaviest bullet I have tried is 210 gr. It seems to work OK for my friends 8.5" Core15 barreled upper though and is a "one-powder" solution for him in that regard. Link to comment Share on other sites More sharing options...

I found that LilGun works well with subs in pistol gas system with .090 gas port or higher. Some pistol gas barrels have small gas ports , I found a 14".5 with a .075 port that would eject and not strip the next round. Drilled the port out to .110 and I got the bolt to lock. I'm assuming the smaller ports was meant for factory sub ammo that uses slower burning powder at the same time balancing for supers......or use with a suppressor.
