I am missing something here regarding T7 and it's corrosive condemnation ..I shot nothing but BP and Pyrodex for 40 years in my rifles ..yes cleaning was so critical you just did it before you did anything else for yourself or anybody else once in from the field ..enter Triple 7 (all I could get in 3F) and my new cap and ball adventure ..purely with T7 as the only energy source my 3 Colt cap and ball revolvers have ever digested ..I use Hoppe#9 and Casey's Bore lead Remover and finish up with 3 in one oil ..no rust no pitting and sometimes I even clean the next day or day after ....
I wonder ..could the guys who had bad cleaning/corrosive problems be running into whatever the chemical make up of Triple 7's residue be interacting with black powder residue unknowingly left from prior black powder use ???
The Triple 7 is simply not acting any different than a range session with an unmentionable ..and is cleaning up about like one too ..in fact ..the easy maintenance of T7 has me "working in" cap n ball shooting where I normally can't/won't do unless I can dedicate (if black powder or Pyrodex) a half day to the effort to load up, drive to range, shoot,drive home, then clean guns which if BP/P takes about 1/3 or more of the amount of time I actually spent at the range! ...
