I talked to the owner of beartooth bullets today about there 325gr ML cast bullets he told me that with 90gr of pyrodex and that bullet with a harvester crush ribbed sabot that they were acheaving the same VOLocitys as a Marlin 444 , I orderd 1 box of 50 in a .429 to try them out , he said thet they could size them any were from .426 to .449 thats a pritty wide range They are running about 3weeks behind on orders must be a pritty good saleing bullets he said that their sales have been booming. once I get them I will post some feed back and range reports for any one interested in these .
