Doe Dump,

** I believe the discussions here have dwelled on 7mm to 308 caliber cartridges with my recommendation being a standard caliber 30-06 (though a 7mmRemMag isessentially equivalent). For the sake of my sub .308 rifles (including my childhood .270; the prairie dog battery: 6mm, 223; youth guns22LR etc), I'd hate to seeyour proposedban on sub-.308 cartridges go thru. No dreaded Mags in any of those places.

** Ah, so it IS a "peanut gallery" thing ----shows.
FWIW, we have had a single documented case where an elk was shot "too far back" with a heavy magnum. It staggered, laid down, and died on the spot where it was shot --- it was an unfortunate, but illustrative example of "having enough leeway in one's cartridge selection for those occassions when things don't go just right". [Of course some folks will jump on that single data point to build their gospel, only on the internet can folks guarantee to "dump" their game perfectlyevery time.]30-06 still remained/remains the camp minimum. BTW some of the earlier fly weight cartridge wrecks we had did NOT involve gut shots.
