Wade, Hornady and Sierra manuals, among others, have loads for various bullet weights. I’ve fired 180s and 167s (so far) out of my 1898.

My gun turned out to be a great shooter. It likes all 3 big name commercial loads (Hornady, Winchester & Remington) as well as my handloads using a Hornady 180 gr. Spitzer. It doesn’t seem to care for round nose slugs as much.

As far as I know, the 180s ate the only commercial loads available. As Ithink you know, the original load for the Krag was 220 gr. RN that was rather long. Those (jacketed) bullets are difficult to find now, although casting your own would be an option.

Everyone here has different stories as to what their gun prefers. Try a few different things in your gun to see what she likes. That’s half the fun!
