This is a great point. I probably shoot 50-100 full house, 5,000+ ft.lb .416 rounds per year and 150-200 375 h&h so that when an animal walks in front of me, I'm confident that shooting the rifle is habit and conditioning. When you get buck fever, your conscious mind takes a snooze and if there is no conditioning, your instinct takes over and that usually results in a miss or worse, a wounded animal
Also recoil is like dark beer, initially it isn't something you would think anyone would tolerate, but you develop a taste for it over time. Eventually a .30-06 will feel like a .223 to you.
The next time you're at the range and a big "macho" guy is dramatizing how tough he's gotta be to put more than ten rounds through his 7mm Mag to his friends, and how it is basically the hammer of Thor. You can calmly sit down at the other end and drop in a panatella sized hunk of brass and lead and sit there and shoot as calm as can be. They'll likely notice the mortar shell impacts in the berm downrange and meander over to see your howitzer and notice the massize empty cases. Then you can calmly reply " oh it's my large-medium bore. A .416". When just the bullet weighs more than most guys loaded cartridges and the shell sends it downrange at more than Mach 2, your always going to attract some attention at the public range.
The longer I spend on Africa Hunting the more and more I feel like a .375 H&H is really a tiny gun.
