According to this guy, the only three chamberings one needs to hunt everything in the U.S.A. are the following:
- 6.5 Creedmoor
- .338 Win Mag
To paraphrase Sheriff Margie in Fargo, “I’m not so sure I’m agreeing with your rationale, there.”
I don’t agree with the rifle choices (the 12ga. is a no-brainer), for the simple reason that they don’t pass the “To Be Found On The Shelves Of Bubba’s Bait & Ammo Store In Bumfuck, Anywhere” test. Granted, the 6.5mm Creedmoor (a.k.a. the “flavor of the month” cartridge) and .338 Win Mag are fine cartridges, but are they sold everywhere? I doubt it.
Also, two chamberings aren’t enough. We can sit and argue the point all day about which rifle cartridges are the best — and I have no problem with entertaining said discussion in Comments, of course — but I am of the opinion that the “hunt anywhere / anything” criterion in the U.S. of A., given the wide variety of terrain and game we have, cannot consist of fewer than three centerfire rifle chamberings, to whit:
- .25-inch (.243 Win, .270 Win etc.)
- .3x (.30-30, .308 Win, .30-06 etc.)
- .3x magnum (7mm Rem Mag, .300 Win Mag, etc.)
…and a credible argument can be made for an additional, larger cartridge for grizzly in deep brush, such as:
- .4x (.45-70 Gov, .458 Win etc)
I know, anything a .308 can do, a .300 Win Mag can do better; but let’s just add a little real-world experience by acknowledging that the .300 Win Mag costs twice as much as its little cousin, and also because recoil / owie shoulder.
All that established, feel free to suggest your three favorite rifle chamberings in Comments, especially when taking the “Bubba’s Store” criterion into account. Explain your choices, if necessary. I’ll be adding mine later.
