Mine is the .300 WSM. I've shot deer with rifles in 30/30,
.243, 7mm/08 and .270. The WSM is just the best rig I've got
right now, and I'm too lazy and broke to have a different rife for everything.
I've actually ruined more meat with 6mm bullets in the .243 than I have with the WSM.
That could be because I'm a little more patient than I used to be.
