I chronographed my krag this weekend, shooting a lyman 311290 mold 210gr gas checked bullet. This is a sporterized krag with a 25" barrel.
imr 4759                   2400
1-1458 fps                 1-1415
2-1442                      2-1485
3-1452                      3-1407
                                4-1446

How much more can i get out of her in velosity and be safe, the brass and used primers look very good but i think the action is the week link.  I plan on hunting this fall with this krag and would like to get up to 1600-1700 fps with here if i can?
