Ok guys, I know this is a 375 RUM Improved but I have heard some unbelievable velocity claims with it. I have heard: 3300+ with a 260 gr 3100+ with a 300 gr and 3005 with a 350 SMK What gives? I have had a few 378 Wbies and none could safely come close to these claims. Are these poeple using 40" tubes? Anyway what do safe loads really produce?
