Recently switching to barnes bullets after shooting tc shockwaves for years. I have tried a variety of bullets and none group like those shockwaves, killed a ton of deer with them but making the switch because every once and a while performance is bad with those bullets. After trying a bunch of different loads and bullets i found myself chasing an unachievable goal. So for my wifes omega, 120 grains of 777 mag with barnes flat 250 tez im getting 0.5-0.75in groups at 100 yards. (Was holes touching with the tc shockwaves). For my pro hunter ended with barnes 290 flats tez grouping at 1.25-1.75 in at 100 yrds with 150 gr 777. Groups with the boat tails with various sabots including harvester sabots never got better than 2 inch at 100 yrd. Most were 3inch groups. Did a bunch of testing with some other brands and never really got better either. I really wanted those boat tails to work better because of ballistics but they just didnt. In telling this to others most im finding are more than happy with 2-4 inch group at 100 yards. So whats your standards?
