One of my hunting buddies has the same rifle in the 270 WSM also, and he has been using it as his go-to gun for hunting season. I use a T3 in 300 WSM, and he also has a 300 WSM. We will shoot at hogs at longer distances, but not game animals. He took an antelope at 286 yds with the 270 as he couldn't get any closer, but that is the longest shot at game animals.
We both reload, and, besides bullet diameter, there isn't any difference in reloading either one. I'm a fan of the WSMs.
