This. Coming out of my troll cave for a bit there is a reason hunting ammo is usually required by State Game laws.OP
What most people seem to overlook is that one must consider bullet construction when hunting. The greatest bonded type bullet is not magic at 100 yards when placement is behind the shoulder and the bullet passes thru before it can expand. Whereas a soft point bullet will excel in the same scenario. When shooting bonded bullets, aim for bone and put the critter down.
I’m aware the 6.5CM is touted as magic on social media but one also must consider the combination of bullet, animal, and distance if a level of performance is expected.
"Battle Rifle" is a sort of nebulous concept that gets thrown around in dick measuring contests about debates over 5.56 vs 7.62
However, the military essentially shoots ball (aka FMJ) ammo. FMJ is a bad choice for hunting (pretty shitty choice for the military too, but that's another topic). In fact many states outlaw them for hunting.
Who the hell cares what kind rifle you use.. Is my old 30-30 Lever Action a Battle Rifle? What about the K98 (german mauser), That M1 Garand, the AR-10? All of them are 'Battle Rifles' Is my FIL 300 Savage Semi-Auto a battle rifle? What's the difference between an M1A and my Uncles Rem 308? Both shoot 308. One of them used by the army, the other an old guy during deer season. In the world of hunting, shot placement, bullet type, energy all matter. Animals don't give a shit what your action is.
Every rifle round since the beginning of time has been touted as 'the next best thing'. There is no perfect round. Everything is a trade off. If you want a long range medium caliber, 6.5 Creedmoor is a good choice
Except 30-06 is perfect. Cause 'Murica
My 10/10 hand to god story: As a "Yute" learning to hunt with my uncle, I saw a deer get pegged twice by a 30-30, once by a 30-06, once by a 270, all within 200 yards. We went over to clean it and the lil bastard jumped up and made a run for it and was ended by another 270 round.
Later that week I hit a deer in the ass on the run and dropped it flat. 1 shot with a 30-30. I'd say it was my superior skill, but it was probably luck as I was 14 and shaking like an earthquake cause i actually hit something.
There is no magic bullet.
