i wonder about the nose on the 260&280 BC cor bon' s siting up againt the primer of the round ahead? i have the older carbine

with tubular magazine. for now i'll stick to jhp's and fp till i learn more. i shot some hornady 300jhp xtp through it yesterday, it's easy to shot accurately with(it's scoped 3x leoupod).
