How many of u neck size?

[hjk]

I was wondering is it really worth neck sizing? I understand that it can make brass last longer, if your hunting you have to make sure the cases chamber cleanly. I have a hell of a time trying to keep constant groups when I do neck size. I have been necking sizing for years, but just like moly coating I'm really staring to think is it worth it anymore? Maybe I'm missing a piece of the puzzle. I don't moly coat anymore haven't for a few years now.

You will probably find that almost everyone in the bench rest arena neck sizes. It may be in combination with a body size and shoulder bump, but a neck size no less.
Most use either bushing dies or custom dies with a neck diameter fitted to give proper sizing according to their chamber neck diameter.
I know of no one shooting bench rest that uses an expander ball on the decapping pin.

If it's a factory barrel, you are practically wasting your time. If you have an aftermarket barrel with a smaller neck, then turning is worth it.

isn't body size and shoulder bump full length sizing i think most everyone is doing this at this time.

You can bet that neck sizing is worth it! If you neck size your brass will last a lot longer and if the liberals get in this year the brass will be worth gold in the years to come.If you haven't noticed brass cartridges have already gone up. Have just purchased 700 rounds of .204 winchester brass, Winchester has just got a 22 million dollar contract from to Navy for ammo. There goes another supplyer. Good Luck Save your brass. craig

The Navy that makes no sense at all since no battles will be fought @ sea and "2 and if and when they use it will it end-up at the bottom of the sea or will they recycle ? and yes "neck sizing" with a "factory chamber" can be beneficial, to what degree ? that depends !

Have you heard of the Marines?

Please explain a little more about neck sizing without an expander ball. Someone mentioned bumping the shoulder body back, isn't that full sizing? I was going through my steps for neck sizing and finding accurate loads for my rifles and think I found my mistake. I shoot full length sized cases with different charges looking for best group. Now that the case is chamber fitted I load the same charge expecting the same good results forgetting that I may have to adjust the load some. Wow!! My memory is sliding down hill something so simple can't believe I did something so dumb. I still would like more info on how the bushing and other dies work. I shoot 22-250 rem and .243 win for my varmint guns.

The idea of neck sizing is to maintain the maximum amount of support and consistant fit of the case to the chamber, with the side benefit of working the brass less.

For the neck portion, a bushing sizes down, and an expander ball style die goes down and up... double the work on the brass. Ball dies are not known for great concentricity and their efforts are without the benefit of controling neck tension as well.

When you think of bumping the shoulder, that is but one of the critical chamber contact areas which a case dimension can be controled. Shoulder, body, neck, "small base" you get the picture. Point is to have control of these areas to maximize accuracy first and case life second.

Hope it helps.
