Just curious...what kind of velocity loss you guys are getting on the Draco as opposed to a full length AK? Anyone have numbers?
Somewhere on here, someone posted that they were getting around 2,150-2,200 fps from the Draco. Not bad at all, considering the fact that you're only getting around 2,350 from a standard AK.
I haven't chronographed one yet. I'm just going by what has been posted by someone who has. Hearsay, if you will.
Yep, this has been discussed many times before. These are general numbers with commercially available ammo (Wolf/Uly/Bear).
SKS with 20.5" barrels average around 2,400 FPS at the muzzle.
AKs with 16" barrels average around 2,350 FPS at the muzzle.
Dracos with 11.5" barrels average around 2,150 FPS at the muzzle.
Mini Dracos with 7.5" barrels average around 1,950 FPS at the muzzle.
The 7.62x39 is a fantastic cartridge for SBRs and the like because it doesn't lose much velocity firing from a short barrel. With less than 500 FPS lost going from a 20.5" to 7.5" barrel, it really makes little sense to not have a shorter barreled carbine. To me, the difference in size and weight ditching all that barrel offsets the insubstantial loss in velocity. Obviously this is a preferential thing, but when compared to the 5.56 or many other cartridges that dramatically lose power as barrel length decreases, the 7.62x39 is much friendlier to short barrels.
Wow..that is actually pretty good. I ran those numbers in Sierra Infinity and here's what I got:
All with 123gr
7.5" @ 300yds 1245.7 fps
56.8 inches of drop
11.5" @ 300yds 1375.3 fps
46.3 inches of drop
16" @300 yds 1517.7 fps
38 inches of drop
Compared to an M4 with 62gr
2800 fps muzzle velocity @300yds 1824.8 fps
26 inches of drop
Yeah...I'd say the 7.62x39 is an EXCELLENT SBR round. Thank you for the information guys!
Maybe we could get this info stickied, the topic seems to come up a lot.
Just copy the info you want and make a post in the Draco Specification sticky.
