Hoppes #9 and Mobile 1
Yup, CLP, we used to get it in the gallon containers! Each of the Gun Ships that carried 50 Cals had at least a gallon, pour it in and fire away. We found out it didnt work so well on the MK 19's, Fire, Jam, jam, fire....The US Military has been using CLP Since 'nam.
If you put your weapon thru more than they do, find something else.
