I'm loading 200 grain xtp & double tap hc with 9.3gn of Longshot and using a cci mag primer in a glock 20 with a kkm barrel at 5.5" long. I have some brass on its 5th loadings and no sign of a bulge. My chronograph says 1275fps. I have about 700 rounds fired and never got a bulge. 22# spring and stainless guide rod.
