It's as easy as falling off a bar stool to duplicate the original gov't load of 220 grain bullet/2000fps using 210-220 grain cast bullets, with a bullet soft enough to expand beautifully and not lead the bore.
Note: don't try to exceed that 220gr./ 2000fps level in a Krag. The Army tried it by increasing to 2200 fps and started getting a bunch of cracked locking lugs, whereupon they dropped back to 2000fps. It was plenty good against Spaniards and Moros, and earned a reputation for being big medicine in the game fields too.
I had a box of 220 grain Hornady RN bullets that I was trying for accuracy. I have concerns regarding "a bullet soft enough to expand beautifully". I've Dyna Bore coated almost every one of my rifles, got a couple lever and slide action yet to do. But the Krag has the coating. The barrel is fairly new and looks good to my aging eyes.
I have several molds in 30 caliber and I'm hoping my new 1898 Krag will be a cast bullet shooter. My goal is ~~ 1,800 fps with 180 to 220 grain bullets.
Question, "Will straight wheel weight bullets fill the "a bullet soft enough to expand beautifully" requirement at those speeds?
