[QUOTE="Coyboy, post: 273529, member: 3733"] Did Clarence give you a report on what he found in the bore? Was the chamber and throat concentric with the bore? doubt it but maybe you got lucky. Was the rifling defect free, from end to end? I assume he skim coated the action to stock and recrowned the muzzle? Lapped the lugs? It helps to know some of the challenges you need to overcome. Before I did any load work I would do my best to brake in the factory tube. Minimum 10 shoot and cleans 20 would be better. I would pick an accurate bullet, work with that and 2 sutable powders to start. Find your max oal to touch lands and back off .025". Load up 7 rounds of each with a powder charge that falls dead center between book starting charge and max charge. With a bone clean bore fire two foulers off the target and the next 5 for group, clean and do the same with the load of a different powder. If one powder shows promise, work with the charge weight up or down a 1/2 grain or seating depth .010 in or out. If those 25 or so bullets don't give you a direction to head, re load the brass, neck sized only and use the exact same oal and powder weights as the original 2 loads. Sometimes the neck sized brass will shoot in the same load that wouldn't shoot in a piece of new brass, somtimes it may be exactly the opposite. This will give you a good start to a promising load, If you get to 200 rounds and nothing meets your needs, get a new barrel!!! OR save yourself the frustration and get a new barrel now. [/QUOTE]
