30-06 Brass

[Catfish]

I`ve formed alot of brass from different cases but never gave a thought to forming 8mm from 06 cases. I guess it`s because I never played much with the old 8 x 57. I`ve got one but never shot it.
Anyway it should be a piece of cake to form them. If you have already fromed some and they will alow a .323 bullet to be seated in the case and chamber that`s all that`s needed. Your FL sizer should set your head space, you may have to adjust it, and you will have to trim cases to lenth. If you get some small dent when forming they will disapear the first time the case is fired. You should also check the case capisity of the formed cases and if it is smaller your max load will be less than book, probibly less than 1 gn. Reduce you max load by the same % that the case volume was reduced. It might also have a greater volume, but I would not recomand increasing max load.
If you don`t know how to measure case capisity you can.
Take 5 factory cases for the cal. your forming for size and trim to lenth. Weight each case empty then fill with water and weight again. Subtract empty weight from full weight and average the weight of the water. Then do the samething with 5 of your formed cases and calculate the % differance.
