I am currently building a double in .303 British calibre. I have already loaded up 200 rounds with the Hornady 174 grain bullet. That is what I intend to regulate with because it IS and WILL BE available, and at a reasonable price. No deer or black bear needs more than 174 grains and in my experience, Hornadys are good performers on game. When Nosler doesn't make the partition in my calibre, Hornady is my fall-back choice.

PS: If Hornady made a 215 grainer, that is definitely what I would have chosen.
