No turn 6 ppc

[Link]

Some must shoot a no turn 6 ppc?

What can you tell us?

To turn or not to turn?

thanks

Yes, I have 2 barrels chambered with my PTG reamer, .272" no turn chamber necks. Using Lapua 220 Russian brass, of course.

Can't prove it, but always felt that my 2 other chamberings, with .262" tight fitted necks are just a little more accurate. Had the reamer reground to a .262" chamber neck, so future chamberings will be with the .262" necks.

A well known shooter, who has done a massive amount of testing in a state of the art tunnel, says that there is an advantage turning PPC necks. If anyone would actually have results to back that up, it would be he. Are you shooting registered competition with the full kit of accoutrements? If you are not, you might not notice the difference. If I were ordering a reamer today, it would be a .263 neck, because I have come to recognize the advantages of more neck clearance, and when I turn for that, in a .262, my necks are a little thinner than I would like. With the .263 I would be back where I started for neck thickness, and be able to use the same bushings.

I think if you are not shooting competition, go 6BR .i think it works easyer and can push a little heaver bullet faster. good for varminit hunting and sometimes longer range.

boyd i'm shooting a .269 neck in my 6ppc and so far i like it. i feel the thicker neck hold up a little better and last longer..dont get work hardened as fast, maybe a bit tougher when ejecting them..all that stuff..But i say so far so good with it...if it continues to shoot as it has been i will never go back to the thin necks.

 

[BoydAllen]

I probably should have explained that all of my actions do not have ejectors. If I were shooting an action with an ejector, I would probably go with the .269, so that necks would be more robust. As it is, I pick cases off of the bolt face.

I own a rifle with a .272 (no turn) neck and have found that after expanding Lapua .220 Russian I still have to lightly turn the necks to get the clearance I desire. For me it seems that "no turn" hasn't wound up being exactly that. However I am a bit of a novice when it comes to ppc , but this has been my observation. I am using my ppc primarily for varmints and I really love it. My 2 cents, Ron...

I have a no turn 6br with a short throat for 68gr bullets and such, just like you would shoot n a ppc. My 6br is a rocket and very very accurate. PPC accurate to be exact. Lee

There is a significant issue as far as shooting a no turn 6PPC that seems to have been overlooked in this discussion. If you were going to use one, you would probably have to use Norma brass, because if you try to use Lapua .220 Russian, that has been expanded up to 6MM, in the expanding up operation, the top of the Russian shoulder becomes the bottom of the 6mm neck, making that part of the neck significantly thicker. On the other hand, in the case of the 6BR, or Norma 6PPC brass, this is not an issue. The case starts out with a relatively uniform neck thickness, although I do believe that there should be some taper, which I believe is probably part of the reason that the typical SAAMI chamber has a little taper in the neck, so that the clearance will not be diminished if a bullet is seated so that its shank is in the neck shoulder junction, where unturned necks are thicker. Although the newest Norma 6PPC brass has been pronounced hard enough, I don't believe that it has displaced Lapua quite yet, and I do believe that those who are talented enough to be at the top of the sport (short range benchrest) use whatever equipment they deem to be the best.

If you use Norma Brass, with a bullet in the neck, it mic's out to .265. I had a reamer made with a .267 neck. I don't have to turn the necks and it all works perfect!

[BoydAllen]

Now there, you've done it.....mucked up a perfectly good theoretical discussion with actual data, that is an exact match for the opening question. ;D
Shame on you!

 

[hedditch]

I'm sorry. ;D

Thanks a lot for the input.

I hate turning brass it never seems to come out 100%. I guess I will have a new barrel at .262 and have someone turn me some brass and get it over with. oh well.

later.

 

[BoydAllen]

Anyone can turn brass. Some learn better hands on, with a teacher right there. Intelligent people vary in their abilities to translate directions into physical actions. You wouldn't expect to be able to play a clarinet by buying one, and a book on how to play it would you?

I come from a mechanist , mechanic background.

Have the tools and still don't like to turn brass.

That's just me.

thanks guys.

 

[skeetlee]

I would think that most could turn brass with there eyes closed. There really is nothing to it!! Lee

Well Lee

It looks like I turned my brass with my eyes closed. Maybe I should open them?

I am trying to get a neck thickness of .0075 and wont hold. I come up with .00075 on one side and .0008 on the other side. Maybe it's my $60 digital ball micks.

I have read many articles on the turning of brass, seems simple. right.

Seems no one has a no turn reamer for the ppc in this area.

thanks. ;D

What tool are you using? are you expanding the necks with a mandrel? What kind of fit do you have on the turning mandrel? What lube are you using?

 

[hedditch]

I've got a no turn reamer you could rent for $30.00. I pay the postage to and you pay it back. 6 PPC with a .267 neck made specific for Norma brass. It has been used one time. I must not have been paying attention as I did not see where you mentioned you wanted one.

I have a PTG .275 no turn neck, with a .060 free bore, in my 1:12 tw, Benchmark barrel. No neck turning required at all, just fire form some 220 russian, trim, run though a Redding type S die, load. Very low reloading time required. This gun is hummer, it really likes the heavier bullets.

 

[BoydAllen]

If you are getting .0005 difference from side to side on your turned necks, you are doing something wrong. If yo give a detailed account of every step that you go through, starting with an out of the box case, perhaps we can identify the problem. Just don't leave anything out. BTW, I think that your meant that you were trying for .0075 neck thickness. You had some extra zeros in there a couple of places. Good luck. I think that your neck turning issues are what need fixing, not your reamer.
