Shooting todays Highwall and Sharp reproduction rifles what kind of point blank range can you get these cartridges (assuming a 6" target so a rise of 3 inches and a drop of 3 inches)- please include powder and bullet style/Weight

Thanks

I can't quite answer your question on point blank but as an example: Shooting BP with a Lyman Postell 528 gr. bullet in the 45-70 and 45-90 Shiloh Sharps and Brownings I shoot on a regular basis at approx 1280 fps::::::Using a 200 yd. zero, it takes plus/minus 3 MOA either direction for 25yds distance changes to hold zero. So this is about 6" high and 6" low between 175 yds and 225 yds. If you want the +/- 3" to stay on the 6" bull the point blank is about 12 1/2 yds either way of 200 yd zero. Hope this helps some. Best regards steve witt

Steve, It sounds like you know your stuff. I have four different 45-70s that I'm trying to find the right bullet for. With the sharps buffalo gun and pyrodex powder what bullet and charge would you recomend at 100 yds to start?

johnas 15: Can't help you much here as I have not shot pyrodex powder in these rifles for several years. I shoot Swiss 1 1/2 in both the Browning 85 and the Shiloh in 45-70. I have found 68 grains, with moderate compression, works well with the Lyman Postell bullet which I use almost exclusively. I do use Fed 215 magnum primers, which many do not, and a .030 veg wad. Swiss gives better velocity then Goex. If I were going to use pyrodex, I'd use the equivenent volume load for 68 grains black. This would be about 54.5 grains pyrodex. I'd start here and see how it does. Best regards steve witt
