Gday Fellas, I know you all are very aware of this bu bullets in the 160gn and up especially the vlds which really do need a 1-9 twist minimum(there will be arguments) need to be tested at at least 200 yards. That is where they get to start doing their best. Those with a couple of stringer shots need to try this before going to radical on mechanical change.Hope that helps a few brothers.lightbulb
