Overall there must be a great majority of Buffalo Classic rifles as they came from the factory with short throats. I would like to hear the specs of powder, charge and coal that you have in your records and how they performed.
I have only started with H4198 and cat fart loads of Unique. My loads of H4198 ranged from 47gr to 50gr with an over all loaded length of 2.440 w/ 350gr plated bullet.
