I wanted to share my new Black Hole Weaponry 6X45 that I finished up yesterday. This one has their proprietary left handed railed upper and BCG along with a BHW 24" SS 3R fluted barrel. The barrel has their B Square fluting and is bu barrel weight under the FF tube and the front is turned to standard gas block size. I had RPG up in St. George, Utah do the upper assembly adding the JP adjustable block for my load work.

The lower is a Kaiser Defense that I put together a few weeks ago. I chose the Geissele High Sped Match Trigger as I want use this one in the short range 600 yard F-class matches here in town and on the PD's up north.

I made the brass up with Winchester commercial cases using my Dillon 650 to deprime, size trim and expand them at one setting. I finished them off using various tools to do all the match prep to the cases as I want to give this one every opportunity to perform.

Black Hole Weaponry has the motto of "No Escape". We all know that in astronomy they tel us a black hole won't even allow light to escape thanks to the gravitational pull. THe shading and coloer on this one all fixed up seems to absorb light just like a true balck hole. A very subdued and understated piece of equipment. The dust cover says it all and I believe it will set the tone for performance.

I'll be posting more as this one starts to develop. Enjoy.

Very cool.

I have been interested in the 6x45 cartridge. Where do you recommend looking for information and data?
 
very nice looking rifle. Hodgdons site list 6x45loads, as do Hornady and Sierra manuals (might be older ones). I have a pet load for my 6x47 shooting 70 nosler balistic tips or w748, that has proven phenomenal on our 60ish pound feral goats.
 
I have been shooting the 6mm/.223 (the 6x45) since the early 70s, and it has served me well. Reloading it is a snap and all the mags for the 5.56 work in it. Anything shot at within 300 yards should be a snap, as this round was used for match shooting in its early life. For a great listing of loads for it check out http://www.loaddata.com
 
I built my first one for heavy steel targets at IPSC matches. I've shot it quite a few sniper matches over the last twenty years and it has never let me down. This new one will let me get in to F-class shooting and I am excited about that.

I have a Black Hole Weaponry 24 inch barrel on my 6.8mm AR. They make a VERY NICE product. And I actually had the barrel at my house within 10 days of my phone call...
 
Just looked carefully at the upper. Does the dust cover interfere with the bolt catch? I think that dust cover there would drive me nuts.
 
Actually I cut the top down off a standard one and the cover drops down to normal height. BHW is getting some extended ones that will come back toward the shooter but their supplier is doing a POOR job in fulfilling their order. If their supplier fails to produce I have DPMS extended bolt catch that will be uber-easy to rework even with my limited mechanical skills.

Shooting left handed it is surprising in that I can extend my trigger finger up and hit the release. I was very surprised how much quicker it is with that set up.

I agree Float Pilot they are super. Mine took a tad longer as it was a custom with the bull/standard configuration and the fluting. I think it looks pretty sharp with the blackening treatment.

It falls right under my trigger finger, but I have pretty big hands. I stopped noticing the brass flying in front of my face a long time ago and I like to be able to single load from the right side of the rifle. It would take too much doing at this point for me to swap over to a left eject upper.
 
I got this one on a whim to test for BHW. I have, lets say, more than a few right handed AR's from tiny to big and I have never had an issue shooting them left handed. I own about 10 bolt guns and only one is left handed yet I don't find converting over to pure south paw any major effort.

I am going to get another LH upper and will probably do a 20 Practical or a 6.8X6 wildcat in the near future.
