Texan, I don't think so. Unless you get the collet dies or the competition bushing dies from redding. I have had alot of neck sizers, and I end up not using them that much. I guess I decided I do this for hutning and not competition.

North Texan:

I neck size every thing that chambersin a bolt action. Neck sizingincreases the life of my brass, and aids in accuracy.The onlytime I wouldI would full size for hunting isif I was going after dangerous game. I have never had a problem chambering a neck sized case. When I purchaseRedding dies, I obtain the Deluxe Die set it is less expensive than buying the neck sizer seperate. I don't use RCBS dies for bottle neck cases, because you have to purhase the Full length Die Set, and Neck Sizer seperate, but I do like their straight wall three die carbide sets. I like to use Forster dies; they offerFull Length die sets, Neck Die sets,Full Length Die, Neck Sizer Die, Bench Rest Seater Die, and Ultra Micrometer Seater Die. They are a little bit more expensive, but I feel they are worth it. Good luck.

Unless you are using a collet or a bushing die, how does neck sizing increase the life of brass? The neck is usually the part that breaks first? I understand if you talking bushing or collet.

I usually just use the FL dies and not size the case any more than I have to. If I am after dangerous game with reloads, I chamber every one of them before I head into the field with them to make sure the chamber. Its not a bad Idea to test even the factory load under these conditind. However I have never had a factory load that would not chamber.

Bigcountry:

When one full sizes, thewhole case is being worked. When oneneck sizes only the neck is being worked. When the case is fire formed, the brass flows towards the neck causing the case tobecome longer, and expand to the size of the chamber.Full sizing causes the case to go back to SAAMI specifications. Continuously full sizing makes the brass expand and contract over and over again.If onebends a piece of wire back and forth over and over again it breaks, the same happens with brass.

Between the head and the begining of the case body is where the brass becomes very thin causing case head seperation. Between the case head and the begining of the body is the weakest part of the case because the case transforms from a thicker portion to a thinner portion.Due tothe brass being fire formed and full sized, the area between the case head and the begining of the case body thins, andweakensbecauseit'sbeing over worked just like the wire and finaly breaks. The area between the case head and the begining of the case body is more vulnerable todamagethan the neckbecause ofdesign, and metal fatiguecaused byfull sizing.

I have thrown away more brass away due to head case seperation than split necks.After every third firing I check for headcase seperation with my RCBS Case Master.Good luck.

Hmm, I have not ever seen that for in years of reloading. I have had more split necks than case head separation. But I always toss mine at 6 reloadings or so unless its pistol brass. Well to each his own.

Bigcountry:

Start measuring yourbrass for case head seperation with a dial indicator type tool, after a case has been full sized over and over again, and it will beover specification for case head seperation before the neck splits, on a neck sized only case. Good luck.

Well you got me there. Never measure it. Maybe you got something. Maybe one day I will have it happen or case rupture.

How many loadings do you see this?

Bigcountry:

I have seenthe begining of case head seperationas early as the third firing, so thats why I start chekingthem then. Good luck.

I'm a little confused[&:]Are you guys saying that you would be better off FL recizing then neck recizing
