Updated?? standard load of bear lead at 1080fps for the LR to todays hyper velocity loads up 1700 fps seems like a solid update. Even bullets them selves from the segmented designs over both lead and iron segmented, shot and the solids of today to several hp designs and all the different lubes applied to them. Bullet weights from 29gr to 60 gr. Even quality of rounds that can as accurate as any centerfire round with in there velocity limits to 100 yards. What kind of change are you looking for or thinking about.
