I would agree with Tom if the Vapor Trails would do anything but vertically string from my BRA barrel. Tried them at multiple seating depths with bad results everywhere. Plus, you cannot get them and if you could, they are very costly compared to the various Bergers and Barts. They do seem to measure out consistently.
After much testing I went with Berger 108's. They are a tangent profile and should like a jump. I jumped out to .030" and gave up. At touch they seem to be the best for me. The only problem is their contour can be as much as .003" different, bullet to bullet. What a royal PIA to deal with if that difference is significant. I have not had testing time to figure that out.
Going to try a .005" jam later this week. Already loaded, I seated them all out more and then varied the seating depth for each one to read the same jam distance, no matter the contour differences. Vapor Trails and even Barts are so much better made. Even my 105 Hybrids are made better.
What your barrel likes is hard to predict. Probably a shame Vapor Trails are so hard to get and so expensive. But, if you want to run with the top dogs, it's an option to consider. The other option is to be like me testing lots of bullets. Now with over 500 rounds through the barrel I still have not found anything that shoots well.
Also, fireform a 100 cases in that barrel before trying to test. I did 50, tested with some results and then the barrel sped up. That ruined all my testing results. By the time I finished fire forming I was already above 200 in round count and nowhere. Get a fireform barrel for anything past the first 100 rd. break-in.
