Mod 0 is the nosler bullet.. I posted this before, blackhills has a perpetual boner for Sierra. They took a trip Sierra and convinced them to put a cannelure on the 77gr bullet. Which lead to the mk262 mod1 load. As they say the rest is history. I just picked up 500, 77gr Sierra for $120 bucks.
Yes, I did find a reference to MOD 0 being the Nosler bullet, not sure how much of it was ever produced. though.
