you will probably find you MUCH MUCH better off with monos by going as light as you can get them for calibre.....eg in poohseventy the 110gen is the best......its a balancing act way more than with cup n core...you dont need mass/weight as it doesnt shed weight...you do need speed as speed/spin help it to open up properly when you do the maths the lighter round starting out faster isnt caught up by heavier round untill you get out past point n shoot range for energy and thus terminal preformance.... thats my take on it anyway.
oh and 6.5/06 just cause its differnt
