Ive loaded some 125g nosler BTs in 308, that have shot very well on paper, I havent yet taken a deer with them. Ive just bought 100 sierra 125gr bullet heads, as they were cheaper!! Has anyone had any experience of these? Looking for loads with varget. They have a flat base. I was thinking of using these on some reds in scotland?, or should i just load up some 150s??
