1863 Springfield hasn't been fired in 40 yrs?
I'd like to begin hunting with an original 1863 Springfield. My dad purchased the gun new through a magazine ad from Springfield Armory in the early '60s. I clearly remember it coming in a wood box and him taking it out, cleaning the creosote off and assembling the musket. It was brand new! Altogether it has maybe been shot 100-200 rounds. My dad hunted with this musket and it was the very first gun I ever shot. After he passed away the gun was stored in a closet for perhaps 10yrs until I retrieved it. Unfortunately, during that time nobody tended to it and it did have some surface rust and minor pitting which I cleaned. The bore was also cleaned at that time using boiling hot water then brushed and oiled, as I remembered my dad doing. It did not appear to have much contamination. Since then I've cleaned it periodically to maintain its appearance. The gun is priceless to me and so has not been fired, just hangs above the fireplace. I shoot a TC modern muzzle loader so am familiar with the general process of loading a musket. but am not sure about this older gun. My questions are: Is there any risk of damaging the musket in shooting it after so much time? Is there a "check-out" proceedure I should follow? How much powder do I use? Can I shoot pyrodox? Will the miniballs need to lubed with a specific type of lube? Does this gun require a wad or patch? Any guidance from you experienced antique shooters is apreciated.
