How about sharing a few doos and donts . I have made quite a few 30 HC cases and some short 308 cases and have found them to come oup pretty straight.

I did have some trouble one year trying to fireform the HC cases without bullets but learned my lesson there.

I brought up the short 30-284 in conversation @ our State Long Distance snd Gary long produced from his Box a small bag with some of them , cut away to show how much materiel thate was in some brands vs others. As I recall, the Winchester case had the least materiel of the ones he had there but I could see what one might be up against if they had to remove all of thet materiel to make a thin neck.

Anyway, any words of wisdom would be appreciated. feel free to email me @ pwass@midmaine.co if you had rather do it that was
