The .243 is a great choice because it can be enjoyed both early and late in life. I was in my late 20's before I owned my first deer rifle but if I had been a youngster I'm sure I would have wanted a .243. I'm now pushing 66 and my last rifle purchase was a .243.270 is a great caliber I live in Colorado around a lot of Elk hunters and I know several people who shoot them. I myself shoot a 2506 and have killed elk at 800 yds with no problems using 117 gr bullet. The first guns I thought my kids would 243‘s and they knocked down elk and deer with it But we hunted on private property then it never shot over a few hundred yards.
