Monster 12” - First Rounds Fired

[SBRSarge]

I looked back in my chrono logs. As a point of reference, the Barnes 110 gr BlackTip in a 12” barrel 300blk gets about 2250 fps or so.

The 6arc has similar bullet weight, better B.C., ~150fps more velocity. What’s not to love?

Now we just need some good subsonic loads and supersonic all copper loads.
