Just wondering if anyone uses bore brushes on there ML'er......I dont really think its necessary to use one but I am thinking it probably wouldnt hurt either.,....your input appreciated
FWIW, I personally believe its very worthwile and always include brush strokes as part of my cleaning regimen...never felt confortable that a "round jag" and soft patch could 100% clean the sharp 90 degree square corners of all the lands and grooves.
Double check my math, but if I have 6 lands and 6 grooves, that's 12 sets of square corners that run the full length of your bore.
Every 12" of bore length is 12 sets of corners that are 12 inches long or 144 linear inches of corners per foot of barrel length.
A 42" bore = 3.5 feet
3.5 feet x 144 inches/foot = 504 inches
504 inches divided by 12"/foot = 42 linear feet of sharp 90* corners to get clean
And, knowing that 90% of time I use Natural Lube 1000 on my patches, and that bore butter can build up, after I initially pump flusing a dirty bore, I run a bronze brush up and down a dozen tmes or so, then pump flush again.
What convinced me was how misleading a "clean white patch" can be as follows:
I got a bore to the point of a clean white patch, then ran a good bore brush up and down a couple dozen strokes...next cleaning patch or two came out almost black with all the crud that the brush loosened up.
So ever since then I always include some brush strokes...only adds 20-30 seconds.
Remember a Dentist's favorite saying:
"You don't have to brush ALL your teeth...just the ones you want to keep"
