6BRA Load----finally!

[moondog]

So, after many frustrating rounds downrange. And a bone head move or two on my part. I got it. Mag feeding was an issue but the Primal right kits work pretty well. The ARC mags, not so much, the PVA kits, not at all, AW mags no bueno.
Kelblys Atlas, 8 twist--left.27" Manners
A-4 carbon fiber, Bix n Andy match.
105 Hybrids -.012" 30.6 H-4895
2955 fps. 500 yards, 6mph from 5:00
5200 ft ele. 3--5shot groups
The shots in the left were DTACs
(They have potential!)

And yes, had paper to the right of the steel.
I just wanted to feel good as someone said.

Nice Bowie Knife!

Just kidding!...Nice group!

Nice group. Have you worked out how best to mag feed this cartridge if various magazines are causing you trouble? I was considering trying to go down the mag fed path with a tactical build on a Kelbly's Atlas action as I have AW and ARC mags at my disposal, but no Primal Rights mag kit or similar as yet.

 

[moondog]

I tried the Kelblys because of the AW cut.
I'm using Surgeon bottom metal.
Not sure what's going on there. Different bottom metal may work better? The problem I have with the ARC mags is the follower would nose dive and jam up. Didn't matter if it was dasher, 6.5x47, or? The PVA spacer kits have a grove that is a bit too wide. It catches the head of the round from time to time. Primal rights kits seem to be working the best for me. I only have the 10 round kits, I haven't tried the 5 rounders.

Pretty well. Please explain.
I have one of these adapter kits but haven't yet used it.

The PVA kits didn't work at all for me. The case heads bind up in the slot when they are offset lower
in the mag. Got two of the Primal Right kits, 10 round AICS style. So far so good, not perfect, but
it's going to have to do. The BR case wants to teeter totter on the lips. I've bent the crap out of em to
see if I could make it better. Sanding the back spacer plate with 600 grit to make it as smooth as possible helps too.The ARC mags have crappy springs and nose dive. I have ordered some
different springs to play with in the ARC mags as I do like the shorter profile 10 rounders.
The Dasher being just that little bit longer isn't a problem in a bone stock mag.
I'm gunna run it next week at a match and see how it goes.

6BR vs 6BRA vs Dasher @ Raton?

Unless you chicken out because of the weather...

I'm running 6BRA in ARC mags, works good for me. Try taking the follower out, then filing back those "wings" on the front half of the follower until they are narrower than the top half of the follower. Finish off with some fine grit sandpaper then steel wool to make the follower as smooth and frictionless as possible. I gave mine a final wipedown with some silicone spray then wiped clean as possible to not leave a residue. That completely eliminates any tendency for the front half of the follower to stick.

The problem is not really a nose-dive, but rather that the front half of the follower gets hung up and the back half keeps rising.

I'm running a TL3 action which is controlled round feed, so that helps some too.

Tried that, no Bueno

I'm a fair weather shooter Pedro.

Bummer, sorry to hear. Seems like the ARC mags are hit and miss.

Pretty sure someone is making a new follower for them and it's fixed all the problems... I can't remember who though
