Interesting Big bore option and a repeater!

I would not use it on Whitetail, but to each his own. When I use to hunt with a handgun, I always thought the 357 magnum as the bare minimum, @ 1000 ft pounds( if I remember right). No room for error that's all. I did take a few deer with a 50 QB forget what energy it had. But used the same standard as I use bow hunting. 30 yards max & behind the shoulder only. Even with my .457 Extreme I limit my shots to 75 yards. 
 
I completely understand where your coming from, however as long as your getting good penetration they are not going far with a 45 caliber hole through the lungs. At 180ft/lbs I got complete pass throughs on several deer and found the expanded epug under the hide on the off side the rest. Of course where I hunt an average size buck is around 150 lbs and does 25 to 30 lbs less. I kept shots inside 60 yards. 
 
 For the IMO rare folks who do shoot for perfect placement, certainly enough power.


So, "Winchester" and stamped made by(for ? cant make it out) Gamo. Looks abit like most modern Korean rifles. .22 gamo's are said to have BSA barrels. Might anyone have the breakdown/lowdown on this one? 
Sold the DAQ .458 when TN outlawed airgun hunting but shot the Misses Bulldog today, and I hate bullpup's ( I think). The darn thing groups very well at 50 yards, very well. Enough to be a recruitment tool to lure in PB types "thinking" about airguns. For me big-bore are a bit of a novilty item but they certainly can be a useful utility.

True, shot placement is where it is at. They was an outlaw in our county I knew well as a kid, he killed hundreds of deer with a .22RF. I ran into one of his offspring at a party recently & got talking about him, he said that his father killed many of them with a 22 short, out the truck window between the eyes. I was going to question that , but he was much younger and more intoxicated than I , so maybe his father did. I do remember one time when I was a kid, a local farmer shot a spotlight of his hand, he never put a light on that farm again.
