The perfect elk rifle/cartridge is the one in your hands when hunting elk. This is not rocket science.
Just make sure the cartridge goes with said rifle. I was reading somewhere where this dumb azz brought the wrong ammo for his rifle when he went elk hunting last year... Forgot who that was...
Interesting..... I have the cartridge name written on my ammo boxes i.e. .270 Winchester,.300 Wby,7x57 Mauser etc.... easy to get the right one.
And for those cartridges which I have more than one rifle,I have the rifle in which the ammo is for. For instance with my FN Mauser .270 Win,on the box lid it reads .270 Win FN. For my Winchester Super Grade it says .270 Win Super Grade.
It's not rocket science.
It isn't rocket science but it does require remembering to change the ammo when you change the rifle at the last second...
On the other hand, it helps to read the labels in the box, something I forgot to do when in a hurry last Friday morning in the dark...
Left to right, .338WM, .280 Rem fired in a .338WM, .280 Rem, .375 Win fired in a .45-70 ( a mistake I made years ago).
Ended up taking my 6x with my buddy's 7mm RM and a 160g Grand Slam.
160g Grand Slam recovered from 6x5 bull, 411 yards, quartering away:
