I just recently picked up a Henry 45 colt and a Marlin JM stamped 30-30. I've got all kinds of data for the 45 but can't find much load information in the 2 loading manuals I have for cast in the 30-30. I ordered some #4 whitetail hunters 165 grain lubed but no gas checks from Missouri bullets. I've used Hodgdon web site and have tried a few loads using H4895. Have ran them from 17 grains to 26. 26 being over max but no issues unless I wind up with severe leading. Ran a few using 10 grains of Unique but am looking for a good hunting load. I'm thinking of ordering some laser cast from Midway with gas checks but want to chronograph these and check accuracy first. Any advise on some loads for these bullets and how fast I should run them and not over lead my barrel? If the lead performs better I am going to start casting my own.
