Hello everyone, my friend just purchased a X Bolt Pro in 300 win mag. He’s loading Barnes TTSX with H4831 about. .090 off the lands. He’ll get 2 shots just about touching and the third maybe 3/4” high right. It’s still very good but I was wondering are some bullets or some bullet designs less susceptible to flyers with a warm barrel. I doubt it but I was looking for some of your experiences. Thanks for your replies and advice. Take care.
