tried the XP3 winchester and my browning a bolt with boss did not shoot well ..i went back to the .180 gr. winchester accubond ..
I have a Sako and it doesn't differentiate between the 150 grain Ballistic Silvertip and the XP3 which surprised the heck out of me. They both shoot lights out. XP3 is an all copper bullet with tungsten in the base so some guns don't like all copper bullets like that and prefer a jacketed bullet. Same things happens with Barnes bullets. Nature of the beast
