Around here you have to drive about 30 miles one way to pay T7 Prices for real black. some of us (me) do not want to order 25 to 50 pounds of the stuff and pay the hazmat fee to use the stuff. So far I've been doing good getting T7 for less than 10.00 a pound at Wally world end of winter sales.
As for cleaning I still feel today that there isn't a much easier ML to clean than a T/C hawkins or sinular type rifle. Remove the nipple throw it in a pail of scalding water with a good amount of dollar store dish soap. several pumps of the water sulotion up and down the bore. Dump out that mess refill the pail with more scalding water to rince. By the time you fish the nipple out of its bath and wipe down the stock the barrel is dry enough to oil and wipe down.
I am amazed at how many I hear and see make the statement of how easy the rifle is to clean effected what they bought.
I guess that is why I see so many cars/trucks covered with road salt and mud is there is no cheap car wash in town and the person won't use a quarter wash as it is to labor intesive.
