I've enjoyed 'finding', owning and tinkering with several Handi's, Toppers, and "Mustangs" [a neat
version of the Topper] over the years. I had a Handi in 30/30, reamed it to Ackley Improved [please, no arguing of whether or not it "is" an AI..
] . I've shot a few deer with them, in fact a 'double', or what was my first "2 deer inside of 30" seconds-something I wondered about when considering hunting with a 'single shot'.
Anyway I also set up a non hunting friend of mine's son when he went to Montana [Bozeman] to college and wanted an 'affordable' deer rifle. I found a Topper for $50, scoped it with an inexpensive fixed 4X, and gave it to him for 'cost' [$95 I think]. Well, he used it to shoot deer and ELK! He still has it and now lives in a mountain home at 10,000' just west of Denver, Col. Mule deer are daily visitors, bobcat, and bear occasional visitors, and he has a beautiful picture of a Mt. lion that was 'down the road' at a rock outcropping near his home. He has to walk in to his home the last hundred yards or so.
Anyway, the 30/30 single shot is a fine rifle. The one that I had in 30/30AI would group the first 3 shots touching, and then sling #4 and #5 shots way out as the tightly fit barrel/block would expand from the heat of firing the first shots. I think I still have the targets and will scan them if I can find them.
