RE: 270...elk cartridge?
Robust, and complete, and specific on point FACTS are indeed hard to come by. Any time you would care to offer any "facts" beyond your opinion we would be glad to look at them.(There has got to be some out there somewhere that "cut the other way.") Remember, actual favorite weapons currently being used by successful elk hunters, not the peanut gallery/theorist/nostalgic variations.
Gross ammo sales would be a classic "proof of nothing" statistic as most the ammo users have never even seen an elk, except maybe in the zoo. Good luck, we'll be standing by.
