It’s been a lot of years ago . I owned two 40x Remingtons. One in 223 , the other in 6-47. The 6mm became popular over the famous 222 and 223 because it was supposed to Buck the wind a little better.
Low recoiling guns became famous for just that reason. A lot of shooting and recoil punishes you.
For what you are taking about I would consider the 308. Very accurate and great for distance you are talking about.
