My reasoning for Whelen is two fold. Bought a allotment of .358 stuff this past fall that had bullets I wanted for my 357 Maximum and Rimless. With the package came 35 Whelen dies and Remington Brass. Also if this economy doesn’t fall right apart I have plans to go on moose hunt in Maine. I don’t have anything for the 30-06 but it wouldn’t take long to round up. 200 gr. Nos partitions would be my direction on the 06’
