Wow!- sounds as if you guys spend a lot of time just getting patches lubed. The method LB noted, takes seconds.
Cutting the pre-cuts is the most time consuming - probably 20 minutes would allow 300 or more to be cut with a race and ball, many more with an arch punch or sharpened hole saw.
Between cutting nicks, then ripping 4 strips cloth and pulling off all the looseneed threads off the sides, all the rolling, unrolling, heating and filding with lubes, I'll wager I can cut pre-cuts amounting to those 4 strips, and lube them in however many boxes are needed - about 60 to 100 to a box depending on size) like LB noted and have them lubed and be loaded & ready to go shooting while you're still rolling and unrolling your patch material, trying to get the lube even. I know it's not a race, that isn't the point - just that the pre-cuts and tin boxes makes patchs and carrying them so simple. Plastic bags? Sorry not for me. Can't imagine opening up and re-sealing a plastic bag every time I wanted to load. Nope not going to happen.
Deltoids is only one-such crappy candy tin box that's available. There are several. Also, the snuff boxes and fireatarting boxes Track sells in brass or German Silver work perfectly.
