[QUOTE="Fiftydriver, post: 60430, member: 10"] Bcraft1111, Yes this is throat erosion and yes this will dramatically lower your velocity and accuracy. Generally you can get some of both back by seating your bullets out farther to get them closer to the eroded origins of the lands. You will never get all the velocity back but sometimes, accuracy does improve quite a bit. For a large round like this I would highly recommend a 3 groove rifling design simply to increase barrel, throat life as long as possible. They also produce a bit more velocity as well compared to a traditional 6 groove. Good Shooting!! Kirby Allen(50) [/QUOTE]
