Unfired pellets only need to be "slightly"concerned with larger bore diameters that may find some moisture creep into the bore wall areas. In that case, eventual hang/misfire may occur... but no corrosion without the heat in short-term hunting use situations. Most-all bores have no such overbore concerns.... just thought I would mention the remote possibilities.

By-the-way....... do you wear glasses, contacs... etc.... andwere not wearing them when you typed?...lol
