Just wanted to complain ... I tried Winchester 296 and it worked grate for 9 shots ... The 10 shot it made a thump sound and the bullet got stuck in my barrel ... It says this powder can have a ignition trouble an suggest that you use a heavy crimp or a compressed powder charge ... Or you can have the problems I had or sometimes it will partially ignight and you can have very high pressures as a results .... I think I'll go back to using 2400 powder ... Thanks hearing my complaint ...
