I've been working with a Ruger 1B in .270 Winchester and have fired about 250 of the 130 Interbonds and while not yet taken any game have some doubts as to their consistant accuracy, Weight has not been as consistant as I would like and groups with as identical loads as I can make range from 3/4 MOA to 3 MOA this defies reason to me. Could just be the one rifle, but I have better luck with other bullets andhave just ordered Nosler Accubonds... nuff said
