Do not use the Nosler Buzzard tips they are noterous for that crap.Their accubond is very good but their E-tips suck.I have a 243 in the Kimber 84 that regulary shoots 1/2 to 3/4 in groups the best I could get out of them was2 1/2 in.Called Nosler, talked to some dipshit,he asked me were I was at.I told him Fl,he said that bullet was not designed to shoot at sea level,i told him I had been hand loading for longer than he had been alive and never heard of such bullshit.
