I started loading my first and only "neck size only" case a while back for a bolt rifle in 7mm-08, using the Lee collet die.
I started with Privi factory loads and am on my second reloading.
The case length is still within spec. which has me wondering.....
If I neck size only this brass and only shoot it in the same rifle, will I eventually have to trim the brass?
Or is case stretching caused more by full length sizing, where the shoulder is repeatedly pushed back and then fire formed to the chamber?
Inquiring minds want to know
