I am a certified "Old Fart" and have fond memories of my father's 1955 Target Model in .45 ACP.
I have used and enjoyed many Smiths over the years on the range and in the field. I have used both small bores (.32's and .38's) as well as big bores (.44 Special and .45 ACP in 1911's) satisfactorily on edible small game with excellent results. If you hit them right (close range - head shots, longer range - through the "slats") there is little meat lost and "you don't have to shoot them twice"...
I lost the vision in my right eye several years ago. I had to quit rifle (I'm too old to switch shoulders IMO) so got active with handguns again. Coincidentally, I was at Bass Pro and they had a 4" 625-8 JM Special at a VERY good price (I must have caught them in a weak moment LOL). At any rate, I picked up the 625-8, added a Red Dot sight and a set of Pachmayrs (didn't like the JM grips). I could hardly believe how well that revolver shoots.
I had a VERY strong urge to add a 5" 625 to the stable. As luck would have it, I trip to the OGCA (Ohio Gun Collectors Association) gave me a look at an Estate sale 625-6 Model of 1989 in as new condition at a very favorable price. CaChing!! I added the Pachmayr grips and a Red Dot to it.
I mostly shoot my home cast Mihec version of the H&G #68 (well under an inch at 25 yards from the Ransom Rest) ahead of 4.0 grs of Red Dot or equivalent (currently Titegroup) and they shoot like this:
25 yards standing:
25 yards standing with the 625-8:
Can I do that all of the time - absolutely NOT but, I do do it often enough to make it interesting...
I mostly use .45 Auto Rims for range use but will often use .45 ACP cases.
I also cast these Mihec 200 gr hollow points for serious use. Driven at 1000 fps they will expand to .80 caliber:
If you want to use it for reasonable range deer hunting (will shoot through a deer at any reasonable range) just use this NOE version of the Lyman 454424 at 900+ fps (safely done in a modern Smith built after 1950 or so):
Easily the most versatile revolvers out there, when you consider all aspects.
Don't get me wrong, I am often found with other revolvers at the range and in the field, but my 625's are considered my favorites for all of the reasons stated above...
