After reading many posts by different names I have found a few myths and misinformation that seems to have followers that perpetuate such.
1. The 45/70 out penetrates the .458 win/.458 Lott rifle. Most who keep this myth running accept a water penetration test by someone who sells bullets, versus the real world of over a century of field use in Africa. You can glue a bullet on an arrow shaft and push it further than either round through the water test by hand; the parachute effect on the bullets and the dynamics of water are the cause and effect of this illusion. The trick of this illusion is the speed of the higher velocity .458 win and Lott, which don't go as far through water ... Geezz, wonder why? Just like slapping water versus just pointing your fingers into it; with this you can see an example of how this law of physics or science works. It is also good ole common sense for some of these snake-oil salesman illusions. Using the same bullets in any animal there is no comparison between these two classes of calibers, either in penetration or in killing the intended offending animal. The 45/70 can out do the big dog? MYTH.
2. Many push this one. NO handgun will suffice for bear protection … I beg to differ. A .500 S&W pushing out 400 to 500 grain solids, Punch Bullets, or 500 grain hard-cast Corbons around 1500 to over 1600 FPS can do anything a 45/70 can do, any day of the week. The caveat here is of course the shooter as with all firearms. Me personally, I have used handguns for over 46 years, with most of that almost weekly shooting. My profession for over 30 years required practice and qualification, and I have taken Elk, Deer, running jackrabbits, one Bear—not hunting, antelope, and I have won medals in International competition. I had my own 50 yard and 50 meter range on my Colorado mountain property, and used it religiously … my life, and my brothers on the street depended on it. This is not for bragging purposes, but qualifications when I say shooting a handgun for me is like pointing my finger, what I look at gets hit … at reasonable range, which is what defense shooting is all about. NO, a guy who rarely if ever shoots at game in the field with a handgun would not be one to favor a handgun, but my handgun brethren out there are. A rifle is better in most cases, but they are too big and inconvenient for everyday carry for some Alaska residents or backpackers, etc. Folks like me up there for a short visit do not mind carrying a big, fat, honking big bore rifle for short term bear protection. Yes, I feel if I ever needed to use my .500 S&W it would perform admirably! NO handgun will suffice?
3. Shotguns are better or as just as good as a 45/70 rifle for protection. If one is talking about a shotgun with a 3-inch chamber, pushing the new Black Cat Brenneke super-hard 600-grain slugs, this has some merit. This would be especially so for country boys who grew up hunting small game with a shotgun. The downsides are few, but here are some. If you carry One-In-The-Chamber, the safety on most shotguns are not as safe, robust, and anti-accident designed as is a good bolt gun, or some lever guns. I feel they are not drop proof, as a good Mauser safety is. If you carry none in the chamber this is a moot point! The reliability of most shotguns is superb, either pump or some high-end autos. The double shotgun seems to be forgotten, but the cowboy version made by Stoeger (http://www.stoegerindustries.com/fir...coach_guns.php ) has promise … with the Black Cat Slugs it would be a poor man’s double rifle! Better? MYTH, as good, Maybe so.
