You are spot on about anti sieze. And with your cleaning process.First, anti seize grease is not the same as what you are thinking. Teflon and blackpowder do not, in my experience, mix well. Also, it is highly doubtful I'll ever remove the breechplug, as PA rifle barrels are more difficult to remove than the tennoned barrels of the western/Hawkin style. For a caplock, I use a piece of small rubber tubing that fits the nipple tightly. Put the other end int a bucket of very hot water and use a tight cleaning patch on a jag. wet the patch and start pumping. It'll pull a vacuum and the water from the bucket will fill the barrel. Continue the process until the barrel gets too hot to hold in your bare hand. Run one or two dry patches through to remove and fouling still in the barrel and let it stand. Oil when cool if desired.
As for the caliber - I want one. I do DO think the .36 carries better than the .32 at longer ranges and, although illegal in my state, the .36 will kill deer size animals in an emergency. Not my first choice, but it can be done. It's all a matter of usage and preference. I don't trust a .32 over 50 yards or on game bigger than turkeys. If I shot like Rach, I may think different. In the words of Harry Callahan - "A man's got to know his limitations" Hope that answers your questions.
As to the .32 caliber round ball. It’s a dandy for skwerlz, rabbits, and groundhogs. 30 grains of FFG was my accuracy load and I used it out to 100 yards, 20 grains was good for the skwerlz out to 50 yards or so which is about as far as I can see the critters. Even 10 grains made a viable hunting load about equal to the 22 long rifle. And I used buckshot and cotton ticking. Very economical to shoot. If my range were to average 70 to 100 yards and increase in size up to coyote, I would likely choose ite .36. If I were to shoot deer sized critters, I would want at least a 40 caliber ball, preferably larger.
William Blane authored a book titled An excursion through the United States and Canada during the years 1822–1823 mentioned muzzle loader ammo by balls per pound instead of caliber.
150 balls per pound was the .32 caliber
100 balls per pound was the .36 caliber
80 balls per pound was the .40 caliber
60 balls per pound was the .43 caliber
50 balls per pound was the .45 caliber
I found it interesting that he stopped at 45 caliber, but to take it out a bit further
.50 = 38 balls
.54 = 30 balls
.58 = 24 balls
.62 = 20 balls
.75 = 11 balls
i do like a front stuffer!
