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

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.
