Mine diffinetly shoots PRB most accurate. As Pahoo stated: range time is a must. If you go with PRB experiment not only with charges but with thickness of patchs. FYI, make sure you have a ball extractor in your range bag. Old Indian says "stuck balls =`s short range trip"
. P.S. Pahoo, hello my friend. Glad to see your still spreading your infinite B/P knowledge
