How fussy do you guys get when neck turning?

[Joe Salt]

Barlow You're not being a smart a$$ thats a good question! I shoot 1000 yard, so if anything like that was to show up it will be at that range. I've seen no turn necks that were just fireformed do very well. And I think all that was done to them was to just clean them up. whether they were 1/2 thou off or more they seem to shoot. Most of the things you hear people say they are doing, someone will disagree with, but if it works for you why then go through all the headaches if you don't have to.

Can anyone prove that a variance of .0005 in neck thickness will show up on target? Not trying to be a SA but just curious. Barlow

I think yes and no.

If you are shooting a tight neck and there is 2 thou total clearance, and some of the cases have 1 thou (0.0005" plus 0.0005")... then, yes it will show up
(I have that tee shirt).

But if you have a no turn neck with 3 or 4 thou clearance and some of your cases have 2 or 3 thou... I doubt it.


... except for the psychological factor.

I lot of what we do, is to make us feel like we have left no stone unturned (that was not intended to be a pun )... when we weigh cases +/- 0.01 grain, and powder charges to 0.01 grain... we are putting our mind at rest.

There have been many tests that have proven that shooters shoot better if they think that everything is the best it can be...

"I've got the best rig on the line and I'm gonna kickass today"

... and when given a rig and ammo and told there is something wrong with it, they do not shoot well.

So, in the end, maybe that 0.0005" really IS important after all.

 

[Joe Salt]

I always feel I have the best rig on the line, And I love shooting again the other best rigs, cause that gives you even more confidants when I win.

L-46 Hey that was my number when I played H.S. Football! And your Answer is. Within 1/2 thou. is all I worry about. After that you're spinning your wheels. Thats the kind of stuff that burns people out. If you have targets better than mine, I won't to see them. And my Wife's count also, cause I did the loading.

Joe...

There was a guy on here about a year ago, who claimed he turned his necks within 1/100,000" (0.00001").

He said he could see the difference on the targets.

It explains my poor shooting

LOL
I think not ???

Hey, you do realize that .00001 inches is pretty large. After all it is 2540 Angstoms. Now you just need to find a caliper or micrometer that reads out in "Angstoms"

Joe,
If you don't mind, a follow up question....how much neck clearance do you run? I think that the more clearance the less critical neck thickness runout may be. When I first started shooting a tight necked 6PPC. my clearance was around .0015. Now I am at around .0025. As I understand it, some .30 caliber long range shooters have gotten their best results running around .005.

[Joe Salt]

Boyd I'm running mine at .003 and I feel a lot better about it than I did at .001. The Extraction is so much nicer. That bugged the crap out of me. Anything I think I ever read, said tight necks were the way to go. NO WAY. I'm not positive but I think the brass is going to last longer also.
What I'm mean by that is when I size it they feel like there going in the die a lot easier. Just feels different! I started doing this part way through the season so I may need more data. Not that they didn't shoot good before but I think I'm on to something.

CatShooter you can still hit the CAT'S alright can't you? I feel at this age if I'm keeping them on paper I'm good. Someday Someone has got to show me how to read one of these Mic's that go that low. Maybe I'm even finer than I think! 0.00001 I'm Impressed. May be that's were this Flyer came from.

Me too.. I ran my 6BR at ~0.001-ish - I re-cut the necks to to 0.0026" and it is shooting better and it is easier to live with.

My 1,200 meter rifle is 0.006"

 

[CatShooter]

CatShooter you can still hit the CAT'S alright can't you?

Joe Salt

Yup...

nearly 4 pages?

neck thickness variations, turned or not, can effect accuracy, with different types of dies,

????
then you can choose whether it matters

 

[Joe Salt]

L-46 Anything can affect accuracy, Especially if its not done the right way. I'd put my money on a good Barrel or a good lot of Bullets! Now you are talking different types of dies? Mine are all made from the reamers I have, so I know there right. I use different size bushings, when I think It needs a little more squeeze if you get my drift. And yes I would turn my necks weather they were no turn or not. and run at least .003 clearance.
Hope this helps, if not you need someone like DR. PHILL!

Not to be sceptical, wait, yea lets be sceptical: just how tight can we claim tolerance?

1/2 of 1:10,000? Did I read this wrong? At what point does measurement become irrelevant?
This is so close that even scientists get Vague.

 

[BoydAllen]

I turn necks the way that experience has taught me works best. They are what they are. It is not like I have two ways of doing it. I get consistent results, and +- a ten thousandth is no problem. Typically I get half that. That being said, recently I have worked with shooters, on line, and on the phone about their turning only to find out that they were measuring with digital calipers. Also, I believe that technique is required to do a consistent job of measuring results. Frankly, I do not believe that mere ownership of the proper tool guarantees that one uses it properly and consistently. When we have these discussions on line, there is a lot that is taken for granted that should not be. As a result there may be some miscommunication. It is the nature of the medium. Ultimately, results will vary in proportion to our being able to figure out the problem, and translate our findings into appropriate actions. I can tell you that we are not all equal in that. Getting back to the OP, it is not so much that I am fussy, it is just that when I am not seeing the results that I am used to, I look for the reason, and usually come up with something. I attempt to fix the problem. Group shooting is about attempting perfection. To do less when reloading would be inconsistent with that goal...for me. In both cases I miss the mark, but enjoy the challenge. Perhaps I should spend less effort on my reloading, and more practicing shooting.

 

[L-46]

I use a bushing die when i can, neck thickness does matter with a bushing die, not so much with a button die.
With less than .0005" variations, you can achieve your goal, mostly.
more than .0005", and you may have to batch cases.
this is not a hard and fast rule, there is always exceptions.
without good feel through your press, you will not know if you hit the mark

 

[Joe Salt]

Boyd and L-46 here is another reason I only go by 1/2 thou. I started using Gage pins to check the inside of my cases after sizing, by pushing them in by hand not in a press. There tapered so they start in very nice. And yes my neck turing is within a 1/2 thou. because I can feel the difference and thats how I sort them. Now I think instead of depending on the bushing and my necks being right, I can tell better by feel. Make sense yes or no.
