Sounds like OP got this out !Good point of reference is to buy can of this....https://www.amazon.com/dp/B000I2079E?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1 In this squib case spray down barrel and let soak...then from muzzle side wooden dowel rod tap out.BTW this stuff can be used to soak in and help break up Rocksett too.Point is, good keep one can on hand........ BTW, would thoroughly clean and inspect barrel after removal.......
