Just a update on my 30/30. Spent the last 3 days soaking and brushing the barrel. Had a brush thru the barrel at least 200 times. Went to the range today and fired 2 shots. Both shots tumbled. Going to keep cleaning until I fly out to visit family in Manitoba. If still tumbling at that point I am going to drop it at Ron Smith and he is going to rebore it to 32 special. Thanks to everybody for the advice. Could rebore to 38-55 but been told ammo is hard to find. Is this true.
