Be careful with the 6mm-30-06 when forming the cases. Was the case designed on the actual 30-06 case or not???? Many of the smaller caliber 06 wildcats are actually built on 270 Win. Brass or 280 Rem. Brass both with a max length of 2.559 so the smaller cartridges will have a longer neck by .065 thousands. Max length of the 30-06 is length is 2.494 and 25-06 Rem. max length is 2.494. Be sure to select the right length case and be sure you trim to the right length. Good Luck on your new gun.
TY Lonetraveler...I was able to find that info on the web..I am trimming to 2.494.and using a lot of caution on this one..
