Sub sonic 7.62x39 for Draco - The Firearms Forum

warriflefan · 10-23-2011, 05:17 PM

I have a draco pistol in 7.62 x 39 and would like to try to mimic the sub sonic 300 BLK round. My draco has an 11 inch barrel. I am looking at the Hornady 30 Cal .308 220 gr InterLock® RN because of the low ballistic coefficient and the heavy weight. I'd like to have little to no flash at the end of the barrel like the 300 BLK.
Does anyone have any ideas on powder or load for something like this?

Looks like I'm going to start with a 180 gn hornady roundnose (#3075) over 7.0 gn of trailboss and work it down to 950 fps. First it looks like I'll have to ream the flash holes to 9/64ths though, and use magnum primers. Of course, I'll listen to any additional advice!
