"The Real Deal"
As my springfield armory shirt says... " Bring enough gun". Very good advice.You're going to need a bigger boat ...
I'm thinking 7mm mag, 300 mag, the bigger thumpers. A bonded bullet as well.
But I'm not spoiled I rotate what I shoot small, big, and all in between. I believe being proficient with them all. My zeros are the same for rifle, then all the pistol calibers are as well. That helps when swapping firearms. But I will admit some are harder to be as smooth as I'd like to be with them.
