"seasoning patches"
I forgot to mention that after my 1st awful range experince (due to bad scope) that I of course came home and cleaned my Triumph. After she was all clean I ran a Seasoning patch down as it's suppose to season the bore for greater accuracy, make cleaning easier...blah blah blah. I put the breech plug back in and put it up. I remounted my new scope when it came in a couple of weeks later and went to the range again. The breech plug was almost impossible to remove! I finally got it out and there was a rust-looking crud around the rings and on the breech plug. I clean the breech plug with a pre-moisten TC cleaning swap and got it back to new.
But did I do something wrong with the seasoning patch?? I have not used one since--DrASUS
