Handi 300 BLK Remington 220gr subsonic vs. Accurate 1680
Posted: Mon Jan 14, 2013 1:12 am
A buddy loaded up some Sierra 220gr Match King w/ Accurate 1680 powder and we crono'd a few vs. Remington factory 220gr subsonics using the same bullet. We had some other firearms to test with limited time, but was able to record the following:
Handi Rifle-300 Blackout 16" barrel with AAC SDN-N6 suppressor
Ambient Temp 40deg
220gr Sierra Match King bullet(same OAL as Remington factory subsonic 2.120)
Remington 300 blackout brass
Remington 7.5 primer
Accurate 1680 powder loaded to 10.6gr
Remington factory 220gr Subsonic 300 Blackout
900fps
887fps
955fps
Accurate 1680/Sierra 220gr 300 Blackout
1027fps
958fps
962fps
Since I had a few Remington 125gr factory Match ammo on hand, chronographed a few:
2275fps
2256fps
2244fps
Next weekend will chronograph a larger string of Accurate 1680 @ 10.6gr and 10.8gr & check both rounds for accuracy..
