Load Catalog: Subsonic Lil'Gun, All Jacketed Bullets

[bamachem]

This thread is a compilation of "Pet Loads" that others have contributed for publication. No chat and no discussion of loads. You can provide a link in your post for the "workup" of the load if you choose to post one.

Any loads listed are what have worked for others, but does not mean that they will work for you or your specific firearm. Pet Loads are NOT a shortcut nor a quick and cheap way to escape the sometimes tedious task of load development. Load development means starting with a LOWER powder charge and working up to that "Pet Load" in a safe and methodical manner, always checking for signs of overpressure along the way. NEVER take a "Pet Load" and use it as a starting point.

In order to be considered for publication, you can submit your information in the following format:

Rifle Used
Barrel Maker, Contour, Gas Length/Port Size (if known)
Barrel Length and Twist
Magazine Brand/Size
Bullet Used (grain, manufacturer, type)
Powder Charge and Brand
Case Used
Primer Used
COAL
Chronograph Velocity, if known or manual velocity, if known.
Any issues or problems, Failure to Fire, Failure to Feed, Failure to Eject, etc. Keep it short.
Link to your "workup" thread

This is an example of a load that I worked up in my AR:
AR15
AR Stoner, Med Contour, Carbine
16", 1:8 5R
MagPul PMAG, 30RD & Custom 10RD (cut down 30RD mag)
110 gr Hornady V-Max
19.6gr Hodgdon Lil'Gun
LC 5.56, reformed to 300BLK
CCI 450 Small Mag
2.10"
2350 FPS (estimated, manual)
Zero Issues so far. All feed, fire, and eject fine.
N/A

Please ensure that your load info is in this format when submitted. Any loads that are incomplete are subject to deletion at any time.

Again, no chat or discussion allowed. Chat and discussion should be done in your individual "workup" thread that you link to.

Thanks!

Spent 20min at the farm working up sub loads in the cab of my truck using my portable equipment.
Just checking for speeds with the chrono.

2 rounds of 6.7gr.
880 & 891fps (did not cycle next round)

1round of 7.9gr
1080fps (locked back on mag)

3 rounds of 7.8gr.
1050, 1033, 1068fps (locked back on mag)

All fired without suppressor. Still waiting on Form 4

Edit:
My go to loading is now 7.7gr of LIL Gun. With my Specwar762 I make 1 ragged hole. Lock open on last round. Tested velocity results below:

someone else's converted brass (3rd time used at least a little short of minimum trim length).

7.6 grains Lil Gun powder.
2nd gen 30 rnd pmag (loaded only 3 at a time)
COAL 2.240
Average 970 fps
Failed to pick up the next round (almost but just didn't have enough oomph to close the bolt)
Ejected brass ok
Failed to lock mag back
*this round had not keyholed and when used with a YHM 3400 titanium suppressor, action cycled fine, mag locked up.

Had the exact load as above with the exception of
7.0 grains of Lil gun. Velocity was low 9's high 8's.
Would not eject at all till the suppressor was on.
Absolutely would not cycle action again untill use of suppressor.
