Black Hole Weaponry barrels - do we like them?


Recommended Posts

My rainier's select 18" barrel(BHW) does real well for its price. It shoots sub moa at 100m with a variety of different loads. My favorite load consists of a 125g sierra pro hunter projectile on top of 44gr of IMR3031. Those little bastards are traveling around 3100fps( per manual, no chrono yet) and my best 3 round group was a hair under .5". I threw together some plinking ammo the other day consisting of m80(147 gr) pull downs and IMR4064  and achieved moa groups, was banging steel mostly with that load.

Thanks blue, you still runnin that dynacomp on your build? I always ran single stage milspec triggers(usually with JP ent. reduced springs) with my AR-patterned rifles, I couldn't believe the difference when I dropped the coin on this SD-E. This trigger feels like she's breaking in nicely too, my groups definitely improved with the SD-E installed.

That's awesome!  I'd be curious to find out what the muzzle speed is on your 20".  Ever take it out further?



no, my primary range only goes to 100. It sucks, a bunch of friends went to the only range in Florida that goes out to 1000, but I couldn't make it that day. eventually i'll hit that one up, at least on the 400 yard range.

I do plan to buy a chronograph eventually too since I am starting reloading the rifle cartridges. up till now I've only reloaded for pistol.
