Those of you using bushing dies.....

Re: Those of you using bushing dies.....
It depends on the case. At least 70%.
If you start to get a bell mouth, you are sizing too far.
I asked this same question a few months ago. There are so many variables nobody could give me an answer then either.

I like 60% - 80%. The remaining 20%-40% helps to center the case neck in the chamber for better accuracy. It is an old benchrest shooter's trick.

That is what I do also. As you develop your load further you can play with how far down you go to play with neck tension. Remember that if you turn your necks and as your brass stretches you can get the "donut"

Re: Those of you using bushing dies.....
I'm using the Redding Type S dies and I resize about 60-80% of the neck like others have said. I likewise feel it helps align the cartridge. If it doesn't, it at least hasn't hurt me any.

Re: Those of you using bushing dies.....
I have just started to experiment with the neck sizing amount. The best advice I got with the neck sizing bushings is to go in .003 increments to end up with a perfect final size.

If you are using redding dies, they now suggest neck sizing .002.
I used to go .003, then dropped to .002, don't really see any accuracy improvement, but I think it might ease up on the brass.
I size to about 60%, then the unsized part does help center the round into the chamber.

Re: Those of you using bushing dies.....
I have been using the Redding bushing dies but in a full length resize version. Seems to be the best of both worlds. I can adjust the body portion to bump the shoulder the right amount but also adjust the neck tension. I do resize the whole neck but maybe should try a bit less based on some of the above comments. Seems to have worked so far.

Re: Those of you using bushing dies.....
I think turning necks would be part of this question. With the 7WSM I size the whole neck, which is not all that long anyway. With my varmint rifles I usually shoot light bullets that don't stick down inside the case much, and with those I size to just below where the bullet will sit. I figure if nothing else that saves working the brass behind the bullet for no reason. I also shoot a 510WSM wildcat and with that I also size to just behind where the bullet will sit so that there's a slight constriction behind the bullet to help prevent oval shaped milsurp tips from setting back when chambered.

The article in my link explains that if you are only partial neck sizing that the bullet will start down the barrel off center unless the necks are turned. The article then goes on to explain that if you are full length resizing and full length neck sizing using a full length sizing and neck bushing die that the bullet will take the path of least stress on the bullet and leave with less influence by any less than ideal concentricity in the case and neck thickness from an unturned neck.
I make a first full neck size pass using a Redding Competition Bushing die and make the final neck and full length resizing pass using a Redding Type S Match FL die. Then I check my handy work using a Redding Instant Indicator. All dies and the indicator are in a Dillon RL550B progressive press. I run each case through the gauntlet one at a time so the ram is minimally loaded. Every case comes out perfect and very concentric even though I do not turn my necks. BTW the fourth station has a Redding Competition Bullet Seater.
HTH!

Read the article I posted above. German Salazar (who is an excellent competitive shooter BTW) has tested many many different combinations. Use your Redding Type S Match FL dies and size your necks in two stages with the final stage less than 0.005". This works very well even without neck turning. See his other articles on the Rifleman's Journal they are very well done. IMO he is very generous with the information he works so hard to produce to improve his scores.
