PTG reamers

[knguyen]

I now have all components for first ever custom build: (ia m like a kid with a new Toy, we never grow up)
my question now is regarding Reamer to pick::

background:
a: Bat MB action
b: Krieger Barrel - 6mm - 1-8 Twist - #17 Heavy Varmint - @ 31" - 1.250 x .900 - 4 Groove - 237 Bore -
c: current redding competition die, redding FL bushing die


what are advantages in going with either
.272" no-turn neck or a minimum-turn .269" neck
i use Lapua brass currently.

I am new to long range shooting.
so , would appreciate from more seasoned members advice regarding which reamer to buy, pluses and minus of either No-neck turn or a minimum -turn 0.269 neck?

thanks alot

I believe in turning completely because I feel it gives a case that is centered in the chamber and if you are going to turn it doesn't take any longer too turn all the way. I also believes it gives better bullet tensions and consistency from case to case. I think at a .268 neck it would clean up completely. You also want to get the freebore right. I would use a .135 for the 105 type bullets. I am assuming Dasher. Matt

Not scientific at all and I, or should I say my arthritic hands, abhor case work however "my" most accurate firearms require neck turning.

Unless you are chambering this yourself, ask your gunsmith for his recommendations.

.272 was the no turn neck version for the old gold box Lapua brass, it had a slightly thicker neck than the newer blue box stuff, a no turn for that newer brass would be .270-.271.

Turning brass isn't difficult and if your smith (or you know a friend) has the tools to do it and is willing to show you what to do as well as how to do it then I'd say get a turn neck version by all means. At the very least you will have learned something.

Why not save your reamer money and let your gunsmith chamber it with his proven reamer?

I use a 271 neck and just make a clean up pass on lapua brass, my loaded round measures just over .268. If you don't turn your brass you still have adequate clearance. I also would recommend a free bore dia. of .2438 instead of the more typical .2435 especially if you want to try the hybrids. I just received a reamer with .150 freebore that I believe may be slightly better than my previous .135 freebore we will see. Good luck with your build.

If you want to know which reamer to pick you call Dave Kiff at PT&G. He's got much more knowledge and experience to share with you than anyone in this site. He can discuss all aspects of the subject giving you the pros and cons of each choice. He makes them and works with the world's top shooters. If you haven't spoken to Dave you're depriving yourself of a real learning experience.

I would go for a no-turn on my first build. No frustration and more time learning the gun, caliber and +trigger time. Once you get that 1st one built (as everyone here can attest) you will be faced with this decision again. By then you'll have more of an idea what you want. Also if you decide to sell the first one you will have a broader pool of buyers.

sorry, iam building a 6BR with this action.
I will ask my gunsmith his reccommendations and also call David for his advice
i am excited, all parts are here now for a gunsmith to finish the rifle.
I am leaning towards a no neck turn. so that for this first build i can just learn to shoot the best i can, and then maybe have a second barrel made which is neck turned.
so many darn decisions to make, but so much fun

^^^^^This is great advice. Getting started in this game , one does NOT need the frustration of ruining brass @ $ 1 a pop. Sure it's not rocket science, but definitely a learning curve until you get it right.

+1 and great advice here. I would neck turn. I used to be able to clean up my Lapua brass with a .002" cut, now it's taking .003-.004". It's still the best brass available!

Count me in as 3rd on this route.

My guess is you will build this 6br and should this whole shooting bug grab hold you'll want an improved 6br (brx/brdx/dasher) next anyway. Sounds like you're doing it right, congrats!
