Just for the heck of it I took one of my new 150 gr LR Accubonds and compared it to a 140 gr BT and was surprised that the length was not all that much more. I'm running a 24" Hart 1-9 so twist rates should be absolutely fine. Can't wait to load up these new Accubonds with some VV 165. These new Accubond's (at least my 150's) have a very high BC (claimed 611 G1).
