I love the Fusion ammo. My Vanguard 270 WSM consistently groups 150grn in the 1/2 - 1/4 inch or less area. I can not however get lighter bullets or reloads from other manufactures to group as well. Anybody else have this problem- were their gun prefers a heavier bullet or a lighter bullet. I havent taken game with the Fusions yet since I just picked up my gun after X-mas but was wondering how do they preform on deer and larger animals.????
