Neck turning

[jmad_81]

How many of you guys do it, and to what extreme?

Been playing around with a RCBS neck turner on my 270 WSM and 243 brass. The 270 WSM got turned down pretty good and the .243 was just nocking the high spots off on some of them and turning the whole neck on others to make them all close to the same.

Is there any real advangate to it?

Not with a factory hunting rifle. Custom bench rifle, probably so. I do have to turn necks for a wildcat I have and have had a friend with a tight necked 270, custom, that required turning. Won't hurt a thing to do it just your time.Rick.

When making brass from another caliber I sometimes turn the outside of the neck. I never do the whole neck, just turn enough to bring down the high spots. If you turn too much it can create a step in the neck junction where you stop, this creates a weak spot the can crack. 340 weatherby from 8mm Mag brass is one example where I do this and 300 wby from 8mm Mag is another. Now days the 300 wby brass is available from several sources so I no longer do it. The 340 brass can be made really easy and is a bunch cheaper than buying Wby cases!

I got into turning the case necks always looking for any possible way to get more accuracy out of them. I used a Forster trimmer with a neck turning attachment to do mine, and I would only take just a little off the neck so that often only a portion of the neck had brass removed. I didn't want to take too much off, yet I figured this makes the necks consistant in diameter, and would help in an even release of the bullet. I don't think I noticed any great improvement, and it is very time consuming. Even as anal as I am, I stopped as I didn't see the point for my HUNTING rifles.

Thats kind of what I though, it would be different if I was shooting a benchrest gun. Oh well I'll just keep telling myself that every little bit counts. I don't mind doing it, but I'm sure not going to rush out and buy a die for every caliber I own.

Thanks

I do not neck turn my brass.

I read an article in Handloader magazine a few years ago where the author tested turned necks vs non turned necks in several rifles. His sinopsis was that turning necks made no difference in all the factory rifles he tested and determined it was only useful in custom tight necked chambers...otherwise, a waste of time.

Turning necks is advantageous in 2 scenarios

1. Tight necked chambers where you need to reduce neck thickness to allow for clearance in the chamber
2. Prior to sizing with a bushing die if you have brass with a neck thickness variation. The bushing die will push all the variances to the inside of the neck where they will effect runout and seating pressure

In a factory chamber with lots of neck clearance neck turning may be benficial to keep neck brass expansion consistant.

I turn all my brass. Does it make a difference? In some cases a lot, some not so much.

Read an article not too long agoe where the author opined that neck thickness (consistiency there of- if I recall correctly) was the biggest factor in brass prep regarding accuracy. Dont remember who wrote it. How/does that that fit into neck turning? I'm never gonna do it. Just trying to learn. Thnaks for the education. CL

Cloverleaf, in the case of brass thickness, it could have different neck/bullet tension. As far as the chamberings in most factory rifles, I've been told there is enough slop in them to not warrant neck turning and some guys say even neck sizing. I do neck size certain brass for certain rifles, however...mainly my varmint rifles, but I guess that's a whole other topic.

I read some article recently about a guy who had set some benchrest record at 500 or 1000 yards and his case preperation was only very mininal, and it DID NOT include neck turning. I wish I could remember the story better so I could find it again.
