I have been loading pistol rounds for many years, and enjoy the work and results. I am considering loading 308 Winchester and have been reading up on that caliber. I have questions about case volume in reference to case weight, with concern about overpressure. I recently weighed a group of cases marked "308win" and found them to weigh 155 grains to 167 grains. I weighed a group of "762 NATO" cases at 177 grains to 181 grains (smaller sample of cases, hope that is irrelevant). I have read posts that "you should load 762's with less powder because of reduced volume". My concern is that the variance within my 308's is greater that the difference between them and the 762's. Right now I plan to only load the 308's. should I be concerned about the variation in case weight? Thanks
