    Hello chaps,

    Just wondered would I get away with neck sizing for a double rifle? The calibre is 416 Rigby and before I get people saying that its not a double rifle cartridge it is for me.

    Thanks a million

    You would have no camming action to seat a round like in a bolt gun. So for loading you want the rounds to just drop into even a dirty chamber without hanging up. This is accomplished best by FL sizing your brass. I don't own a double but the same applies to most single shots. The name of the game is reliability for me.

    FL size, your life might depend on it.

    Fair points made. I only ask as I'm in the market for some new loading dies and saw that rcbs make a neck sizing set for 416 Rigby

    Of course there is.

    Let's just say that you need to drop two in quick. They should drop in by gravity and make a distinctive thunk-thunk sound and not need to be pushed in or possibly being jammed down the barrel by closing the weapon

    When a full length sized case is fired in a chamber , it expands, hits the chamber wall and actually by impact with the wall comes back in a bit. A case that is only neck sized doesn't bounce back it again and will only get tighter on every additional firing.

    And though you might not think so, the Chambers might not be perfectly the same.

    I just sold some doubles and I told them that if they ever took up loading to full length these or any dg rifle as your life depends on the case going in and the case each and Everytime without fail.

    Neck only sizing went out with high button shoes. Full length resize every time for consistency.

    As Von said, the loaded rounds need to pass the plunk test. Remove the barrels, make sure the extractors are fully seated and drop the round in from about halfway inserted. You should hear the rims hitting the recess in the breech, and there should be a distinct plunk/thunk.

    The fired empties should also fall out with just gravity.

    These outcomes are best achieved with full-length resizing.

    Sorry for piling on. But if you are going to use your double on DG, there is no reason not to full-length size - and your life and the life of others could depend on this.

    If you're trying to extend the life of your brass by virtue of not working the entire case, I can see that. My one and only neck sizer die if for 7mm Rem Mag. I used it once. The rounds I took to the range with it were somewhat tight to close the bolt on. It was significantly harder to raise the bolt once fired. Was it due to the Arizona heat? Was it due to shooting a max load? Maybe a little of both......I don't know and I didn't care, that was the end of necksizing only for me.

    If I am just planning on shooting paper then neck sizing will lengthen the life of the brass.

    However all of my hunting rounds get full length resized and all area test fitted into the rifle that I will be using. I have seen way too many rounds jam up when trying to load them with any type of rifle action.

    I sold all my neck sizing dies and my groups shrunk. I also do not use the neck sizing buttons. I deprime on a dedicated deprime die and full length resize with Redding type S bushing dies.

    So how many times do you plan on loading each case?

    For what it is worth I full length resize new brass as well.

    I usually keep my hunting loads separate from the ones that I intend to punch paper with or build up reloads. And as far as building new loads I am fine where I am at now for all of my rifles.

    Other than that I have some in my hunting loads that have been reloaded 5 times with no problems, and some as many as 10. But I do agree that case life will suffer with full length resizing but that is the price I pay to make sure that my hunting rounds will chamber. I watched one of my brother in laws miss a shot opportunity on a real nice pronghorn one year just because a round would not chamber completely. Then once we got back to camp we checked out the rest of his reloads and out of 50 there were 15 or so that would not chamber at all and another dozen or so that were way too tight when the bolt was closed. Now if you can get neck sized rounds to chamber with little effort then go for it but in my single shots both rifles and pistols I'll continue to full length resize my hunting loads.
