Nice weather. Shot the 38/55 at 100 yds. First 3 had a inch and half group. After that accuracy went down hill. Had barrel cool and still not as accurate as first 3 shots. I'm using H322 powder. I see many suggest 3031 powder for the 38/55. I'm going to try that and see what happens. Darn cases get stuck in chamber. I have followed suggestions for that and nothing helps. i use a wooden rod to push them out. Looks like I'm using a muzzle loader. The brass is really hard to remove. Any suggestions as to how to loosen up the chamber.
