In NY you got 3 months to get a deer. Still too lazy, go next door to PA for january flintlock.... Get with a farmer, you can hunt does in the summer with permits. They still don't get enough deer harvested.....
Fancy and ultra modern is great, but good old basic equipment gets the job done. A spray with windex and a bore swab and external wipe, corrosion is gone..... Even if a bit of residue remains. Wouldn't push it though. Clean her good. Clean everything in the safe good. Got a great looking homemade 45 caplock from the 1960's and a great looking glenfield model 30 30-30. They were taken cared of.
Personally, I use 20:1 water and ballistol. After a shoot, I do q quick wipe down and swab the bore with a wet patch or two, then a dry patch or two. When I get home I clean it good. I use windex in a pinch. Moose milk is similar to ballistol n water. Many miltiaries, including the USA still use blackpowder for artillery and use ballistol n water to clean. I store with WD40 when cleaned. I check it the next day for grime / rust and clena more if needed.
I leave clean guns loaded the whole season till I use it. No problems, no failed ignitions. If it's a wet rainy day, I change out the load. I put in a soft case and bring inside to warm up slowly. Quickly warming up exposed to air ciculation makes condesation on metal. I try to put it in the coolest art of the cabin or trailer. I Dry patch the bore bore loading. I then use a lightly oiled patch with WD40 to get a light coat on the bore to prevent rust while outside or for that season. Even left guns loaded from october season and still worked fine in december.
Clean the breech plug in soap and water, clean that flash hole best you can. I use a drill bit with my hand and twist the gunk out. Do not store the breech with oil, do not store in the gun. Leave the gun barrel muzzle down to drip out any extra oil. Do those things, the gun is exremely reliable. Never had a problem, never do a fouling shot with a cap. Long stick goes boom.....
