[myfxr1993]

Hi! if there are any fellow gunnuters out there that can help me with any information on the steps on how to resize 7mm remington ultra mag brass into 26 nosler ,I have a browning x bolt in 26 nosler on its way to me and have only been able to purchase 1box of 25 pieces of 26nosler brass for $104.00 plus tax, and i know that the original 26 nosler rounds were head stamped 7mm rum. Any and all help is appreciated. I will include my email address if anyone would like to just email me. myfxr93@hotmail.com thank you regards Darcy
