Been shooting the 1898 Krag sporter more this year than in the last 20... got on this cast boolit jag via a Gew 88 and now been fooling around with the Krag . I read somewhere that the Lyman # 311284 was designed for the Krag. I been loading this bullet sized to .311 and 20.5 gr AA5744 @ 3.130 ". Neck size only and at this OAL boolit engraves as the round chambers. Shoots as well as most of my jacketed "go to" loads at a fraction of the cost/wear and tear...really enjoy this rifle, especially with this cast boolit hobby...Tedly
