Hey I just bought a handi-rifle in 22-250 and have shot about 23 rounds through it. I have been Winchester ''White Box" 45 grains in it with fair accuracy out to 100 or so yds. Yesterday I reloaded a few rounds with a Lee Handloader. The six rounds I reloaded won't fit in the chamber. Or to explain it better the round will fit but the gun won't close and lock shut. Upon closer inspection the once fired round has a very small ridge about a quater inch up from the base that is about half way around the case. Is this a normal thing in a Handi-Rifle? When i get a set of dies for my Lee press will it remove this ridge? I need some serious help. Thanks in advance.
