300 AAC BLACKOUT

Just a survey of existing bullets that people may normally wonder about. It is clear that some new bullets should be developed to be optimal for this velocity range.

Great info...the 110g Vmax looks like a great HD load. I noticed that was 16" barrel, could it be safely driven to ~2100 or more in a 10.5"?

The .300 AAC Blackout/Fireball/Whisper has great potential, but is absolutely in desperate need of purpose built bullets, as most 30 caliber bullets are designed for the much higher velocities of .308/.30-06/.300 Win Mag and are not optimally performing at the lower velocities.

Ideally an early upsetting, barrier blind loading of around 100-110 gr or so with about 13-16" of pen and good weight retention would be introduced. Until then, the 110 gr VMAX is probably the least bad option of the less than ideal performing bunch noted.

Before I had the gel test done I polled people and only 9% picked the 110 Vmax as the best supersonic bullet. It is interesting to compare the actual results to what people thought before the results.

Which bullets look best for deer hunting?

Is the Hornady 123gr V-max purpose built enough for 7.62x39?

I'm getting 2150fps in my 10.5" Noveske with the 110gr V-Max. It is supposed to be in spec for 300BLK (I got it before the 300 BLK hit the market). I'm using 20.0gr of W296 and a pistol length gas system. As with any handload, start low and work up and use at your own risk.

I tried some Sierra 110 Varminters and could not get them to feed. I will have Brassfetcher test them anyway - as they can be used in bolt rifles.

An expanding subsonic round which feeds in an AR is something I plan to get developed in 2011. In addition to the loads which are out now, I am working on six more factory loadings with LE/self-defense/hunting supersonic ammo being the highest priority (after the 123 supersonic and 220 subsonic which are already a done deal).
