I love barrel cleaning threads, !!! only thing maybe better is "how to lube your BCG" threads or go to a Harley forum and check out "whats the best oil" to run in the 3 holes threads, it can get pretty funny/scary? LOL
The old guy that helped me during the first of my shooting/reloading experiences in the early 80s or late 70s would pour a little extra ammonia in Hoppes #9...And let set over night. Think that's all we had available
And wait....he also neck sized!!!!
No hammer marks on his bolt like some would say
That bull barreled 6mm really shot like s___T, now that we have the internet im realizing that thing was a smooth bore after his cleaning method (no lands left I guess) and he was talking of shooting prairie dogs all day at 500 yds. in montana. (no pics then it didn't happen right?)
But he did have pics of his camps with deer hanging like a string of fish...man the good old days
