Thread: Neck turning...is it worth doing ?

+1

I have been annealing all except the thirty rounds also .
I have gone whole hog on all except the thirty rounds which have just had the primer flash hole cleaned up internally and a shoulder bump. Again just to see if there is any measurable difference in accuracy with identical loads over the full treatment cases.

I will be interested to see if you can see the difference or it just gets lost in the noise of all the other factors that come into longer range shooting.
And if you do notice a real difference between the two brass preps whether then annealing that 30 bring them into line without neck turning.

if its a factory chambering...NO

if its tight neck custom chambering, you are best to

I neck turned because I had to, used mil surp .308 and necked it to .260 but I ended up with 16 1/2 thou neck walls and the loaded rounds wouldnt fit my hunting rifle. Dont bother neck turning my TR rifle yet ( notice the yet) dont think I will.

Correct. And even quality cases like Lapua and Peterson have variation. My last lot of those 2 brands in 308 displayed around 0.3 thou variation albeit a very narrow band. One of the worst in the quality line was my 7,5x55 SR Norma cases.

The other thing is if using brands that have wide neck thickness variation eg 1 thou and sometimes worse , turning may fix that but usually there is an accompanied bad weight variation. Weight variation can be assumed to be capacity variation ( some would argue not, water capacity testing is the only accurate neasure).

And yes the other one I have had is an indivual case that no matter what, always displayed runout when reloaded.


PS: @small_caliber I still have a box full of Precision Shooting magazines going right up to the time it folded (with half my annual subscription left to run). The quality had dropped off in the last years but still some excellent reference material in them.

LOL just realised I had all the tools sitting here......quick tootoo,gee it makes the neck all nice n shiney with a very light skim...... just need to find some walnut shells to bash up and will try out the tumbler too...no excuses for loosing brass when its all shiney like.

I use short grain rice in my tumbler. It's works and it's cheap.

cheap....I LIKE that idea...will give it a whirl.
