OK FAL SHOT... let's talk about this for a moment. Your first paragraph could have some merit too it, if you would have established what you consider tolerate recoil along with accuracy and your idea of what a hunting weight rifle should weigh in at.
Now buying ammunition at "Mom & Pop" stores is not where re-loaders as you mentioned in your post go to for ammunition and from what I've seen nor do many others regardless of where they live.
As for practicing long and hard to get the most out of a weapon, sure why not, most have too do that just to shoot a .22 long rifle well.
As to "YOU" out shooting most the people on this forum, that's a pretty bold statement chief; only speaking for myself... I'm sure you might… but I guarantee you'd have to shoot to prove it. Pounding your chest in print doesn't make statements facts, explaining might help in your case.
As to your 7mm Mauser remark; you did pick a very fine cartridge to allude to; but your history is a little wanting in facts. Walter Dalrymple Maitland Bell aka: Karamojo Bell did used a 7mm Mauser, as well as a 6.5x54mm for his Elephant hunting… but from what I've read on Mr. Bell's hunts his .303 Brit had as many kills as both the other aforementioned cartridges combined.
Oh by the way'.., dating the cartridge really is not necessary here; most, and I mean most here already know it.
As for your paragraph with the rant'.…"narcissistic wet cartridge dream" in it. Come on, you know that's inflammatory, and based on what you have already wrote... I'd say; it's very telling on you as a marksmen and hunter. You, like all of us here; have the right to state our opinions "a view or judgment formed about something, not necessarily based on fact or knowledge" when asked a question(s), which you have given. And my opinion is, you're the one with daydreaming experiences and a metric ton of bovine anal seepage.
So I hope you'll be happy with your 7mm Rem Mag and kill many critters and punch much paper at great distances with little felt recoil, along with consuming copious amounts of Odoul's non alcoholic beer from your favorite Mom & Pop store while you buying your 7mm Rem Mag ammo for your hunt….
Just trying to be funny, don't take it personal.
