    For varmints ? Why not rezero ?? Get a data book and keep track of your dope for what you shoot , then you can switch back and forth willy-nilly as you wish .

    Only makes sense .

    The more intense your accuracy needs the more anal you need to be.

    For example one of our SWAT team snipers uses only two loads for his rifle, one for barrier and one for open shots, and he has his data down. Now on his entry gun he zeros with the duty ammo but shoots practice ammo. He considers the POI difference between the two for entry purposes unimportant.

    Our pool patrol rifles are zeroed with 75 gr TAP but we practice with 64gr Win Ranger. The difference isn't much for those purposes.

    For nailing varmits I would rezero or at least know the difference for POI. If this is a self defence gun only I wouldn't worry about it.

    The idea would to be zeroed for varmints, but not worry about the 77gr zero when going between rounds or having to pick it up for SD

    On a side note, the difference in max rise between the 60gr vmax and the 77gr SMK is about .4 to .5" a bit after 100 yards, assuming a 200 yard zero. I'm not sure how that would translate if the zero wasn't calibrated when switching from the 60gr to the 77gr. Guess I'll just have to get out to the range and shoot the 77's and see how close I am at ranges and see if I find it acceptable. As mentioned, the 77gr I keep for a SD situation...which equates to relatively short distances in all reality. I keep 77gr on hand due to the fact that it's all I shoot from my mk12.
