There’s not enough real world difference between a lightweight 6.5 creed and a heavier 300 Norma? Really? Someone’s taking crazy pills.
And, within the confines of the criteria I laid out and the game I intend on taking, I’d say there is a Goldilocks gun. Not too much recoil, not too little energy on target, not too little barrel life, etc.
Nothing you said was of value here, and it didn’t need to be posted.
