Outrider27 said:Years ago I bought 2, 5000 patch bales of surplus GI .30 caliber cleaning patches, which are cloth and square. Don't know what their dimensions are, but I always took a pair of scissors and cut each square in half, then each half square in half. Those 4 quarters of a GI .30 caliber patch were always perfect for .22 barrels. 8) I still have part of one bale left....
I also make square patches, determining the best dimensions for each barrel and rod combination, using off-white color cotton flannel bought on sale by the yard at fabric stores or the fabric counter at stores like Wally World. I keep meaning to take a block of wood to use as an anvil and cut out round ones with an arc punch, but I never have gotten around to that.
