I loaded some 148 gr lead HBWC and some 148 gr HBWC plated Berry bullets with identical loads of 3.1 gr of HP38 . I tried both tonight in my S&W 52. The lead performed flawlessly..the plated bullets almost all stovepiped. Another shooter suggested that there is less friction with the Berry bullets and that does not build enough pressure to operate the action effectively. MY conclusion is that I will need to load plated bullets slightly hotter. Is this a likely explanation and correct inference?
