The Krag is a very easy cartridge to handload for. I shoot predominantly cast bullets from mine - the Lee C312-185-1R sized .312 cast from 100% wheel weights. Powder charge is 19 gr of SR 4759 which is an excellent cast bullet powder. As the above post stated, watch for seasonal brass and buy in bulk. I use a .303 British neck sizer to neck size only. The brass will last a very long time that way. For pig hunting loads, I use H4350 under either a 180 gr Hornady round nose or the 220 gr Hornady round nose. These bullets are not as accurate as cast as they are a bit undersized for my bore.
