Wash new material twice, once with soap, once without soap, then hot dry in the dryer.
WWWF + a tich of oil, couple ounces of Neetsfoot oil per quart of winter windshield washer fluid - slows evapouration in the hot summers here and the fluid doesn't freeze
when shooting in the winter time.
No matter what lube is used, the patches are wet, not just damp.
I also sometimes spit lube them and again, WET. Dragging a patch over your tongue is not spit lubing a patch.
Neetsfoot oil or Track's Mink Oil for hunting.
I suspect the 11 ounce would measure about .024".
For years I used nothing buy 12 ounce in my .69, as it would not shoot anything thinner. In the last 10 years or so, I found it would not shoot the very much thinner
10 ounce denim. That ball size is .008" smaller than the bore which is a true .690". I also shoot .690" balls in the .69 using the same .021" denim patch. Due to the amount
of lead moved when seating into the muzzle, you have to want to seat it there. After introducing this combo into the muzzle, it is easily pushed down to the powder.
Currently, I use 10 ounce. The material I bought a year of so ago, measures .021" compressed.
The previous few meters I bought, measured .0225". So different makes do measure differently.
The current 10 ounce shoots well in all my guns, including with .690" balls in my .69 calibre rifle
or with .495's in the .50 and .360"(as well as .350") in the .36. I use .595's and the .021" in my .615" bored 20 bore smoothie.
They are only snug for the first 4" of the bore, then drop easily due to the choke.
There is ZERO gas cutting of the patches, which I expect is due to the balls actually obturating.
