Similarly, we shot many of the old Speer 85 BTSP that were designed for deer in the old 1/12" tw 244 Rems. Those bullets worked very well in our 243's and 6mm's, but then, so did a few others. The old .243 Partitions killed countless deer for our family, and many fell to the old Speer and Sierra 100gr's. Most fell in their tracks with only a handful traveling a few yards.
While often in the South, we hunted and hunt with all types of various calibers, cartridges, loads and bullets, with very long hunting seasons and very liberal deer limits, sometimes one per day, we had the luxury of trying all types of cartridge/bullet combos on game, including handguns. And that didn't include any cull permits for the farms.
Always being an experimenter, back around 1980, I began playing even with 22 cals for deer, and soon learned proper bullets and good shot placement made many 22 cals very effective on deer and then hogs. Once the heavies, VLD's, bonded, and monos came out, it became a very different world.
Below are a few of the various 22 cal bullets we've used in various cartridges to take deer sized game from short to mid range (NRA standard). Bullets used to kill deer but "not shown", 55gr Hornady SP (ceased using in early 1980's), 62 Barnes, Nosler 70gr AB, Speer 70 SP, Berger 80gr, and the Hornady 88 ELDM. ( I grew tired of digging through the deep shelves of bullets)
