I have a rem700 ml 50cal. I got it many years ago when I was a teen and had only experience with cleaning cf rifles. I cleaned the 700ml the same way shooting pyrodex. Needless to say I experienced some rusting and pitting. The lands are pretty good with some minor pitting in the grooves. I get decent accuracy now with pyrodex rs, 1.5" hundred yard groups with sabot and cast boolit. My question is: does the bore have to be pristine to paper patch or is a mildly neglected bore ok? I don't want to buy a mold if I will be wasting my time.
