This is all academic debate now and I find it interesting, so by no means take me as trying to tell you I’m right. This is my favourite part of discussing hunting rifles around the fire, the minutia.
I’m of the opposite thinking on thick bush cartridges. We’re in what almost certainly vies for the nastiest bush in Canada, the Pacific Northwest rainforest, and the thought of something taking a death run into devils club or slumping under deadfall on a 40 degree slope out of sight is anxiety inducing. I do understand the meat damage argument for those primarily concerned with net poundage in the freezer, but find that quality modern bullets pushed fast only really jello the parts I’m not interested in eating anyhow when placed correctly- ribs and organs. I see “meat damage” as proof of “terminal ballistic effectiveness”.
Tests have shown an 1,100fps 400+gr .458 bullet is disrupted as much by brush in flight as a 2,850fps .30-06 or even faster .270, that is to say there is no such thing as a brush buster, that’s a myth. I can understand the desire for a soft recoiling rifle, which the mild medium and big bores are, but so is a .243, .260, or 7x57 and you don’t sacrifice the speed or trajectory. In BC non-expanding bullets, such as the hard cast as preferred in heavy and slow big bores like a .458x2”, are of questionable legality as well. Many will spit their coffee at that statement and have been using them for years, and feel the regulation only applies to FMJs and intends to prevent the use of military ball for hunting and I agree that was the initial intent. I personally have my home and hunting business on the line have no interest in testing the meaning of non-expanding bullet in court.
End of the story for me is make it quick, not stupid quick just finding the animal at 2,500fps or higher impact speed when inside a couple hundred yards, and a lighter for caliber quality bullet. It’s remarkably effective at putting animals down, offers marginal recoil in all standard chamberings, and has a far more workable trajectory. The heavy and moderate stuff I feel is from a bygone era of poor quality expanding bullets that were unreliable, and powders and actions of yesteryear. This said I’m a nostalgic type and love the .404, .318, etc or at least the idea of them. While the .318 isn’t slow the .404 certainly is, but makes up for it in panache. Likely the safe for you with the truncated .458, it’s just “cool” and I get that.
This build has been short listed to include one I didn’t put on the list and applaud the thread input for that, down to .404 Jeff, .375 H&H, .458 Win, .318 WR, and 7x57.
