So with these now being out for some time now. what is everyone seeing as far as BC. With my rifle I'm seeing.291 as a number that works well for me. I've actually shot some of the smallest groups personally with these. they seem to be met with some criticism at first, and there seem to be quite a few nay sayers out there. would like to hear about any other feedback as how they shooting for them. I'm mainly concerned with lot to lot consistency, before I pull the trigger on a few K.
