44 Magnum puts the 357 to shame
It isn't even close.
Look for an early, black & white, to mid 1970s handloader annual type magazine. Inside you will see some men punching holes thru a 1955 Ford Fairlane rear bumper with a Smith 29. Hey, if it's in print it's true. Right?
I have personally 'kilt' many a landfill microwave, as well as all steel conventional, stove(s); as well as but limited too T.V.s, & steroes, speakers and turntabes, American and Japanese; refrigerators and freezers, stacked and conventional standing; air conditioning evaporators and condensors, pressure and non pressurized versions; water heaters; Detroit sheet metal from every Rust Belt manufacture riddled from numerous angles and distances; All...obviously... from under the watchful eye and in strict accordance with all state and federal safety guidelines of course (yea, right).
You kids & Nannies out there, don't try this at home. We are the professionals.
Conclussion: The .357... can't /don't /never will/aint gonna...hold a candle to Mr. 44 Mag when it comes to penetration.
As to the Hog & shoulder penetration question: Are we talking a grain fed Kalifornia beast, or some East Coast Swamp critter? I have the medicine for both.
