Advice? 115 gr 9mm load for m-11 smg
Gun is an M11-9 with a Lage Slowfire upper. I am loading on a dillon 650, with dillon dies. Using x-treme 115 grain plated round nose. Titegroup for the powder. CCI 500 for the primers. I have read many guys on uzitalk are running 4 to 4.5 grains with berry's plated 115 RN with great success. They didn't mention COAL.
My loading manuals are calling for 3.7-4.3 for 115 gr Lead RN, with a COAL of 1.100. I am putting a very light crimp on, just enough to take away the bell. Chambers in all my 9mm barrels, as well as my dillon case gauge. I loaded up 10 at 3.7, and my smg is a single shot. So I bumped it to 4, and then finally up to 4.3, and it still doesn't run. Stovepipe after stovepipe, sometimes it will eject spent casing but then will send next round nose up, jamming the action. The mag runs flawlessly on factory loads. When I attach a suppressor, it runs perfect at 4.3. This load also runs in my glock and xd, burning pretty clean and not too snappy . I am seeing no signs of over pressure, and am wondering how much higher I could safely go to get it to run. I definitely don't want to do any damage to this gun. I don't have a chronograph ( I know I need one), What would you all suggest I do from here?
