Which one is the best to use? And is it worth it for accuracy on a hunting long range gun? I use Nosler brass for my 7mm rem mag and for my 7mm Dakota I use Norma brass. I have never turned a neck but if will increase my accuracy I will by one, so I need some opinions guys. I like to get as much accuracy out of my guns as I can squeeze.
Thanks

Neck Turning

Neck turning really only applies in a rifle with a CUSTOM CHAMBER (tight chamber) mainly for benchrest shooting. In a hunting rifle with a factory chamber you would be wasting money and time. Bill
 
Neck turning is not only for tight neck chambered rifles. I have turned my necks just to clean them up to the same thickness (or within .0005) in my no turn neck 6BR target rifle.
I have also turned my 22-250 brass to clean them up for Varmint shooting.

I know it helps to keep bullet runout to a minimum. If the neck is the same thickness all the way around then in theory it should help size the neck concentrically, seat the bullet straight and also release the bullet concentrically when fired.

Shooting is a 90% Mental/10% Physical game. If you have 100% confidence that you have done all you can do to make your rounds as accurate as you can then that is a good portion of the mental game taken care of right there.
 
To reap the accuracy benefits of neck turning really requires the custom tight neck chamber (refered to by b72471) where the cartridge neck to to chamber neck clearance is held down to one or two thousands of an inch.
Neck turning for a SAAMI speck chamber that have clearances of ten thousands of an inch in the neck area is a moot point.
I neck turn for my .22 PPC tight neck bench rest, and would never consider this slow proceedure for any SAAMI spec chamber.
A far easier way to explore accuracy gains is trying some match grade bullets and primers............these I do use with fine results in my SAAMI spec chambered target rifles.

neck turning for reformed brass

I reform .30-06 brass into .257 Robt. (just because I am cheap) and the area of the case that used to be the '06 shoulder is now the .257 neck. I have WAY too thick of brass in this area and must turn my necks for safety. It doesn't hurt much in the accurracy dept. either as my Sako shoots like a laser when loaded right. Anyone reforming brass down in caliber would have the same problem or blessing. Imagine reforming .308 brass into .243 Win that fits your varmint gun like a tight, custom, target chamber.

I agree with that. When you start neck turning you can SEE how bad is the uniformity of most factory brass. Neck turned brass has more uniform grip on the bullet and low run out is the name of the game if you want to improve accuracy of your reload..any reload. Sinclair have very good one and the new eccentric adjustable mandrel must be nice :)

Not correct. Uniforming the neck has these benefits even with a factory chamber:
- same pull weight case to case.
- same pull all around the neck --> even release of the projectile
- and the big one: you can go to neck-only sizing with a bushing system and toss the expander. Less runout, and better case life all else being equal (don't thin the neck out too much with the turner). Also less hassle with the expander gone.

Having said all that, if you're OK with 2" groups, neck-turning is a waste of time. If you want to squeeze .5" groups down a bit, it's time well spent.

I use a K&M, and have used the Sinclair. AFAIK, the K&M is the best available: easiest to adjust, most features, best price. Hard to beat all that. Bruno Shooters Supply sells them, as do others.
