Jerry, I've been loading 300 grain hollow points (Sierra, Hornady and Remington) for deer with my 45-70 for 30 years. I still have several hundred Hornadys from a Midsouth Shooters supply OEM seconds sale a few years back. However, the past couple of years I've been loading the 300 grain Speer UniCor hollow point #2482 (2.53" COL) over 55 grains of H4198 in Winchester brass with CCI 200 primers. Great deer, black bear and hog load. Cedar swamps or clearcuts, it will work.
