Not trying to open a can of worms here but saying a 44 magnum handgun is less than a 30/30 rifle needs some explaining. A 30/30 is a super deer gun at normal deer ranges, say out to 150 yds, the bullets are soft & they work great. When I was a kid an old 30/30 Marlin brought home several deer, just stick the barrel in their ribs & pull the trigger, don't try to make a traget rifle out of it or you'll have wounded game on your hands.
The 44 magnum handgun has cleanly taken every animal on the planet, up to & including elephant, would you try that with a 30/30......with any bullet? A 44 with good, hard cast slugs, flatnose & driven to good velocity is a proven killer all over the world because those hard, flatnose slugs drive straight & deep, causing massive amounts of damage, the slug is already about 1/2" in diameter & running at 1200-1500 fps the destruction inside is a sight to behold.
The "paper" energy of a 30/30 will outshine a 44 magnum, in the real hunting world that 44 magnum will out do it easily. Just as an aside, a 22-250 has more "energy" than the 44 magnum, you wouldn't use it on a moose or elk.
This is the 3rd bear we took in 08, I called it in to about 40 yds.....actually I called in 2 at the same time, I was looking at one bear, my son, who was facing me at about 30yds so we could watch each others back was looking at a second bear, neither of us knew we had 2 bears in close, he killed this one with his 270.
This is #17 between me & my 4 son's, all spot & stalk.
