To the credit of the OP, his hunt is in October, and it’s now March. We’ve all seen posts on here when the hunt is two weeks out and the poster is asking for load info. The OP has plenty of time for load development and lots of range time to develop data.JMHO, but I'd choose one bullet, and stick with it for all your shots. Trying to make a last minute cartridge change in the heat of the moment is a recipe for failure. Again, JMHO.
