That is exactly the way I went into purchasing these calibers.
Only missing is my 12 gauge, might have to take another picture haha
.30-06 can be as light or as heavy as most would need for North American big game, the 7.62x39 is great for under 100 yards of fun on most small animals and even deer to a degree.
45-70 is like tossing around a football with friends and the 416 is when Godzilla attacks.
