Who makes the best remage prefit barrel?

Mmy current favorite is Black Hole Weaponry / Columbia River. BHW uses polygonal rifling. I've used a number of others but never liked any of them as much as BHW.

I've been considering trying a Black Hole. Would you share specifics on yours? How does yours shoot for you? What sized groups are you getting?

Ok, you asked. Pardon the wall o' text.


My 7mm Rem Mag was the first Win70-Post they'd ever cut. It's a 24" 10 twist specifically for shooting 168's. Thing is a laser beam. Makes 3.5" groups at 550yrds like it's on sale. Easy to load for too. Almost whatever I put in it shoots. Unlike my 28" shilen 9 twist which doesn't like to shoot almost anything. I sent them my old barrel to verify the threads on and they turned my new barrel back to me in under a month with a custom made barrel nut. Pressure signs are lower on this barrel than on my Shilen too despite almost identical similar chambers and the shilen having a really long throat.

My 26" 8 twist .243AI just came in a couple months back. So far it's making .3-.6" groups and has made exactly 1 group over that that wasn't plainly my fault. That's at just about 225 rounds fired in 10 different loads. My 45.5gn RL23 load with 108 ELD's is making 3178fps with SD's of 5fps and making half inch groups at 100m.

My 7 twist .223rem 26" barrel on my Mossberg MVP .223 lets me punch higher velocities than I'd otherwise be able to get without getting into high pressures. If I don't jam the bullets then I can get 73 ELD's and 75 Hornady HPBT's to 2950 before the load is max. To my knowledge this is the only drop-in barrel nut using MVP barrel ever made for the .223 platform. There was a miscommunication from me when I ordered and it got delivered with Savage small shank threads so I had to have the tenon re-cut but that was not expensive or a big deal and it was my fault. I sent the wrong machinists drawing. They do have both now.

My first .223rem barrel from them was a 18" AR-15 pipe. I spent a year beating that tube up. Never cleaned, shot fast, junk ammo. It's always delivered despite my efforts to prevent that. Still boringly accurate.

My 2nd .223rem barrel was the same as my first but I was nice to it. It made .5-.7" groups with whatever I'd stuff in it and <.5" with loads I tried to make good and actually developed. It got shipped off on a trade. Wish I hadn't done that.

My 6x45 barrel from them was a one hole shooter almost regardless of load spec. To my knowledge it still is.

I tend to push my loads hard, usually above book for that little edge at matches or just to be excessive. I've noticed that I can routinely go just a bit over where I can with other enfield type rifling barrels before pressure signs show up. I usually get a marginal velocity increase but sometimes it's notable. Velocity gains are inconsistent across barrels. My .243AI turns in exactly the velocities I was expecting.

When I call them and ask for something unusual or off-book and tell them, "yes I know it's ok I handload and wildcat and I don't mind if I need to trim necks I want your tightest benchrest chamber" they promptly make me what I asked for and trust that I have the skills I said I did. When I called up asking for stuff they didn't make, JP got on the phone and we went back and forth with dial micrometers over the phone till a spec was reached and then I got exactly what I asked for.

If you want easy, they have easy. If you want serious, they have serious.

Here's my latest full-house .243AI load development target w/ 10 shot groups:

And the .243win 3-shot fireforming loads for .243AI from my first run out of the gate.

I have two different prefits that I'm running. I have a pva rock creek in 6x47 that is 3/8" or better with 107gr smk. I can make headshots with it on a silhouette @700yds. Just tested some 108gr eld and 105gr vld-h for hunting season. All three are under 1/2 moa @ 500yds.

I also have a criterion 7twist 22-250 running 88gr eld that's a **** laser out to 815yds. That's where I've been limited until I go back to k&m. It is truly a 1/4 moa barrel/ load if the driver (me) doesnt mess it up
