Neck turning brass

[hybridfiat]

I think that case length will be of greater concern to the average shooter. After a few loads the case will have flowed into the neck and you will need to reduce the length and get all the cases consistent.
If accuracy is of primo importance then by all means take a whisker off the outside of the necks to get them uniform. For normal hunting it isn't going to be a priority just something to do when waiting for the next day out bush.

Reforming brass and wildcatting are totally differnt spheres to the usual reloading and often requires more drastic actions. When a case is shortened by more than the normal trimming ....................... say shortening by a few millimeters the new neck is now formed from what was the case wall and as many case walls are tapered and often thicker at the bottom that the top the new neck is of thicker brass than the original so requires thinning. This was often done by reaming but case neck turning seems to be the new fashion.

I helped in making some cases for the 6.5x53 Rimmed Mannlicher cartridge using 303 cases. It required numerous steps and neck reaming to get the neck thickness right. The forming dies had a neck reaming die. It was interesting but not exactly my idea of normal reloading the cases had to be then loaded with a fire forming load to finish forming them to the chamber before proper reloading could be commenced. I only helped out the once ...................... mind you he did not shoot the rifle that often but it seemed a lot of work really.

I still do a lot of case conversions as some of my rifles don't have proprietary cases available. Neck turning is mandatory as they simply wouldn't chamber otherwise.
I neck turned my (benchrest) Field Rifle 6mm BR as it had to cloverleaf at 300m. My .223 cases very occasionally get a brush up as I do shoot over 300m with it.

cheers guys, not interested in wildcats etc or case conversion. Simply the benefits of neck turning.

anyone had experience of improving brass life by neck turning, by getting rid of doughnuts?.

cheers

Sorry no .................................. but then never had this doughnut problem that I can remember.

if you're not shooting a tight neck rifle or converting brass The only way it's going to improve brass life is because your wasting time turning instead of shooting.

As stated in my original thread above I am already achieving good results. I simply wanted to know if there was any benefit from neck turning.

From the replies and useful articles I don't think I will personally be taking it on as an addition to my reloading ritual of annealing, crimping etc.

Thanks all all for sharing your advice.

I was trying to be subtle but if I have to be direct then so be it; No, don't waste your time.

Tam,
neck turning will not improve case life. Annealing will

 

[deeangeo]

Tam, neck turning will not improve case life. Annealing will

Spot on

 

[Tam the Gun]

Ok then, rephrased.

will neck turning improve case life by getting rid of doughnuts?.

 

[Conure]

I am thinking you need to suss out why your getting the doughnuts in the first place.

As I understand it unless you have a tight neck chamber as many bench rest rifles do you are wasting your time neck turning and may be actually making things worse by increasing the amount the case neck has to expand to fill the chamber mouth.

Yes there is turning to suit a champer. But a light skim can increase uniformity and concentricity.

Having read a few internet threads on neck turning since starting this thread, i am now happy that neck turning can be used to best effect for uniformity as stated above. I have also seen that without its use on a set of brass I have reloaded 12 times annealing regularly has had little impact on the accuracy of the ammo.

I think I am going to park the idea of going to the extra effort when my current efforts are working well. thanks to all for the input.

I do it for the .284 Win but only because its necked up Lap 6.5 .284 brass. Its a pain in the t.ts to be honest, what does mr Foster have to say on the matter ?

 

[Reiver Boy]

I have just ordered a rifle in .284W and have been told that I will have to turn the necks of the necked out 6.5-284 Lapua cases that are the most accurate to use. I am assuming that they won't chamber without being turned down, but I'll find out when I start.

They do chamber in mine but there is quite a variation in the brass thickness after being stretched.

trust your well. Just read up on what Nathan Foster has written on the subject in his reloading book.

For my situation I have concluded that unless accuracy is likely to improve then it is a non essential task for my non-custom chamber.

im going to steer clear until my group rises a nats whisker. Thanks for the steer towards the orical (Nathan Foster).

take it easy, shoot straight.
