When my Dad got old enough that his venerable Parker Double 12 was too heavy to carry any more, he went to the LGS to buy a Model 29. The Sales Person shifted him to a Model 57. I developed loads for him that he could handle. He was proficient enough for deer hunting.
I inherited the gun. Last year when my made changed to the range, they prohibited Magnum anything. I bought some .41 Special brass (a wildcat) and developed loads for that. Easy, peasy, comfortable and accurate.
No matter what you shoot, reloading is the answer. If you don't want to do that, for whatever reason, stick with rimfire or target loads .38. Lots of options.
On another note, I shot .44 Magnum handguns for deer for many years. I just got it in my head that I wanted a Thompson Encore in .308 Rifle. BOY, what a kick that gives. My scope even has 4 sets of rings, not 2. I changed out the std. wooden grips for Go0dyears (oh I hate rubber handgun grips), but it made the gun comfortable to shoot. (off season I put the wood back on so it doesn't make my collection look awful.....LOL)
What's the barrel length of the m57? Is there a difference between 41 special and 41 magnum if you use the exact same load other than cartridge length?
Yes on reloading. I'm learning and just bought some tools. Will be slowly learning how to reload 32 h&r magnum first.
