I recently picked up a cardboard box of smaller boxes of bullets at an estate sale. There were six ALL yellow boxes of Nosler bullets in .30 cal. Two were 150 grain, and four were 180 grain. The boxes were still "sealed." When I got them home and opened them, they all have the wide cannelure cut. Anybody have any experience with these? I load tons of .30 cal partitions in about ten rifles but no experience with these older bullets. I will try them, but any quick tips or comments?
