Alpha 6bra reamer

[03machstock]

Anyone have any luck with an alpha 6bra reamer? I have a 6bra barrel now that shoots like crap with ~350 round in it so I’m pulling the plug on it and starting fresh. Going to order a bartlein blank, found a new gunsmith. He said he has 2 reamers, one was an alpha 6bra .135” freebore. I’m going to be shooting Barts hammers in Peterson brass with varget preferably, pending what the barrel likes. I also have 105hybrids and n540 on hand. Would the alpha reamer work with these components or should I ask him more about his other reamer? I’m looking for something that hammers out .3-.4” or smaller 5 shot groups that’s not picky.

As far as I know, you can use Peterson or Lapua in an Alpha chamber though DEFINITELY not the other way around, as myself and a ton of others have tried it.

What’s wrong with your current setup? It’s really hard to make a BRA shoot worse than .350, like you’ve got to try hard to make one suck.

This one sucks. Chasing my tail since day 1. Fire forming loads never showed promise so after about 120 of them I tried to do a quick load development but anything I went back to never repeated. It hates 105 and 109 hybrids, and varget. I worked up a load with n540 and Barts hammers, but nothing repeats. Just when you think your on to something you re shoot it and it shoots like shit. My buddy suggested loading up 20 of my best load and shooting 4, 5 shot groups so I did. It would shoot all 4 groups totally different. Anywhere from a .35 to a .9 and everything in between. I went back and forth with the smith trying all sorts of experiments but I’m done throwing money at it. Iv tried 3 primers, 5 bullets, 2 powders, but the only thing consistent, is that the barrel is not.
I’m going to start fresh with a bartlein and a new smith.

How many scopes?

How many scopes?

Only 1 scope, but it’s on an origin action and I switch back to my .223 barrel and it still shoots as it should.

Sent you a PM

Sounds like something mechanical may be amiss.

Similar issues with my Alpha reamed barrel. New barrel, new brass, and Tuner. Will not shoot consistent. Sent scope to Nightforce and they sent me a video of them beating it on a bench to say its all good. Going to cut an inch off and rechamber to see if it shoots any better.

I have an Alpha reamered BRA with .120” FB. Initially used Alpha brass but switched over to fire formed Lapua. Zero complaints with how it shoots

Once in Great while you get a barrel that is C... even name brand ones, looks good thru a borescope ?

Yea, can’t find any “smoking guns”. Gotta pay to play I guess.

135 fb may be on the long side for the hammers. I use a BRA with 104 fb and don’t think I’d want it much longer. The Gungnir may be a better fit for that fb. I use them with 150 fb in a Dasher. If you’re sticking with Barts he could provide better info. He also has the Dagger that would likely work with the 135 fb.
