I get it that you just want a 300 H+H.Your preference is justification enough.And you may order your eggs cooked the way you want them,be attracted to whatever sort of woman appeals to you,etc.
If a man wants to build a gun,he can do it his way.I just bought a Krag that was sporterized in a fashion inspired by the NRA sporter.How much sense does that make?
Just general info,no push intended,my 30-06 AI would chrono 2900 fps with a 180 gr Accubond.My 30-338 would get 2900 fps with a 200 gr Accubond.
But I understand our OP is not looking for numbers.
A guy just might want a 7x57,or a .405 Win,or a .250 savage,or a Willys Overland station wagon.
