Looking back. I would say: 243 Win. 308 Wen. 270 Win.
I don't think I ever had a deer run off after I shot them with a 243. More dead right there than not, with the other two.
I did a run with a 7-mm Remington Magnum, I shot a lot of everything for a few years as well. Moose to rabbits. Most any and all will work fine for deer. Need to put the bullet in the right spot.
