Ran out of room some how, here is the rest.....
using a 127 grain, flat-based bullet.

The .310 load is for rifles which are over-bore.  As you may know, many Krag rifles came from the factory with bores ranging from .309 to .312.  In rifles with bores significantly larger than .308, jacketed boat-tail bullets do not give very good accuracy.  The .310 load will be intended for use only in rifles which have been “slugged” by a gunsmith, and shown to be of at least .310 in actual bore diameter.

It is our intention to provide year-round choices to owners of these fine old rifles, lest they come to be regarded as an "obsolete" caliber and slip into obscurity.  We appreciate your support in this regard.

That is the news we have at present.  Contact me if you have any questions.
