1.25"x1.25" is the perfect size when soaked with #9 using a jag that is .275 diameter and pushed through the boar with 15# of pressure applied at a constant rate. . . . . .
Are you kidding? Get some scissors and cut the darn patches until they fit. Screwing up a couple will cost atleast 1 cent.
I'm far too cheap for that.....I tear off pieces of paper towels (the good stuff, not the cheap, thin ones) and use them. Never had a problem with them....
