The 120 VMax is very accurate in my 7mm WSM
. I am using it for long range coyote hunting
so as to reduce the chance of a ricochet. I know there are bullets that might carry further but that's not my primary concern.
With a full charge of RL 22 and 215M's I have had a number of one hole groups as far as 200 yds. I am still working on the bedding on the third stock on this M 70 Classic.
As to what would happen on a deer I have no idea. I don't think anything wants to get hit by this bullet however.
If the bullet you are using now is working at long range I think you should be very happy and just keep using it.
