Gunsmithing DELETE

[Tigerfan601]

I’m wanting to order a reamer from PT&G to start a 6BRa build. The only sheet I have found so far is a .271 neck and I’m pretty sure I need a .272-.273 neck. I was looking for the Freedom Gunworks .273 neck with .120 free bore but haven’t found it yet. Anyone have any information or help on the best reamer for my application? Thanks guys.

I went with the 274 neck and 135 freebore

What bullets are you using in yours? I’m planning on going with 107 SMK’s or 109 hybrid

 

[MachoMan]

107 and 109. Haven’t finished it yet but that’s my plan as well.

I’ve decided to change to this reamer. .273 neck
.125 free bore.

Second reamer print is the one you want and aligns with the commonly used specs from the original Alex Wheeler print that got popularized. First one I would not recommend (base too small, shoulder too large, neck too tight).

I’d have to agree with you. After talking with a few gunsmiths they all tell me the 2nd is a better option and will work great. That’s the one I ordered.

Jgs BRA #1 is Alex wheeler design. It's sweet

my BRA remmer is from JGS..... .274 neck and .104 freebore i shoot 105 and 109 hybrids both of these bullets are above the neck shoulder junction at .030 off the lands...personally i wouldnt go more than .115 on the freebore unless your going to try and shoot 115s.

This is very close to my standard 6mm design. .273" no turn nk and .103" free bore. I use it in 6xc, 6 Dasher etc. when running 105/108's. Great set up that yields tight accuracy.

My reamer From Pacific Tool and gauge I got a 6mmBR reamer with .272" neck and throated for a 87 gr Vmax.

I have never had to turn a neck of Lapua or Rem brass. The accuracy is amazing

I use .272" neck and .104" freebore, shooting 105 hybrids.

This thing impresses me every time I take it out. Not uncommon at all to shoot 5 shot groups at 100 yards like below. I fireformed some more brass at the range yesterday, and I was getting results like this:
