I lucked out and found some 30 cal. 165 grain nosler solid base bullets at an estate sale and have killed deer loaded in a 300 win mag and 30-06 with them and they worked flawlessly. My pet load for my 30-06 and these bullets shoot into 1/2 moa. I can't seem to get this kind of accuracy out of the accubonds and it frustrates me. I haven't tried the bt's in this rifle so I can't compare the two, but like I said the accubonds don't perform like I think they should.
