The other afternoon was sighting the CZ 455 .17 HMR when I felt something strange on chambering the new round. Carefully drew back the bolt and found that the bullet tip was just showing out of the neck of the cartridge case. All I can think of is that it must of happened when closing the bolt forward as it was alright when loaded in the mag. Could this be why some rounds are getting stuck in the barrel? Most/All the gasses going around the bullet before it enters the rifling . First time I have had any problems, this was a fresh batch of Hornady Vmax 17g
