. . . That gives me hope that even my Krag with the .313 grooves might work well with the C312-185-1R GC'd boolits [sic] I have. . .

You may be overlooking the importance of fitting bullet to throat diameter. If a cast bullet doesn't fit the throat, particularly a long one like the Krag's, it can yaw before engraving off-axis on the lands. This can result in significant instability.

Please consider spelling "bullet" conventionally. The intentional misspelling always makes me a bit queasy, mostly because I worry that anti-gun zealots will use it to ridicule us as ignorant bumpkins. We don't need that.
