Neck sizing vs full length

[David Milisock]

It's a different kind of sticky. It is a "click" at the top of bolt lift on a fired case and it is nearly 100% prevented by bumping the shoulder .002 to .003" with a properly sized FL die on each firing.

People are of course fee to do what they want, but virtually no experienced competition shooter concerned with the ultimate in accuracy neck-only sizes.

I'll have to look for that in the future, my rule has been if it won't easily open with my pinky finger I should back down.

Some very good info here, but haven't seen any comments on initial prepping. What do competitors do to their brass before first firing when it comes to sizing. Do you fl size with the die set as manufactures instructions or do you use a different method?

That is why most top rated 1000yd Benchrest shooters have gotten away from the long narrow cases. Short and fat to minimize the Banana affect. It’s proven.

Humm
This doesn’t sound like anything I’ve ever heard of, perhaps a deep state secret.
Personally I use a BR case because it shoots smaller with less recoil etc.

Ok I took a hard look at all my bolt action rifles, 1 Remington 1917 in 30 06, 1 Smith Carona 03A3 in 30 06, 1 custom Remington 03 in 358 Norma, 2 different 03's in 30 06 a Springfield and a Remington, a custom 700 Remington in 6Mm Remington, a custom Howa in 223, a 96 Mauser in 6.5 x 55 and a custom 98 Mauser in 450 Marlin.

Leaving the cock on close actions out of the discussion. All the bolts when opened from an empty chamber with my right pinky, have a small click the last couple of degrees of rotation.

If I open the bolts easily, rotate most if the way and then it takes an extremely slight more effort the last few degrees and produce a slight click when this happens.

I always lightly grease my bolt lugs but I looked for wear and even on rifles in which I've fired thousands of over 60,000 PSI rounds and I see no appreciable wear. Yes bluing has marks but all the rifles lock up tight and there is no gouging on the bolts nor in any of the barrels.

I guess I never noticed any clicks when opening the bolts on my rifles in which I neck size because it does not exceed normal functions. I always fire a round open the bolt pocket the brass and close the bolt.

I saw a T-shirt that I interpreted as making fun of neck sizing at the F-class nationals last week. It was a picture of a target with impacts all over it in an open choke pattern with a caption "I NECK SIZE".

When working with in perfections, one has to do what ever one has to do to try to minimize the imperfections. It worked for me in the past. I have since moved on to more consistent components.

Yeah . . . a funny shirt. It suggests an accuracy issue with neck sizing, but actually the issue is really about extraction. A more appropriate picture then might be a large mallet striking the bolt handle to get it open.
