Ok so had a good friend of mine that had a closet treasure of a Japanese Miroku Kentucky style rifle in .45 that he just let sit for years (how sad). I bought it off him for $60 bucks, which leads to first question...... Is this a reasonable price for this recreation of a cool piece of American History? Supprisingly it was not in bad shape at all. some very minor rust spots on the barrel that came off with just a little oil and rag. The barrel was in supprisingly good shape. I did a good hot water and soap wash with a good rinse off and then a solvent cleaning and that barrel came out clean and bright. My main question here is pertaining to maximum theoretical powder load. I shot 60grn. ffg pyrodex out to about 40yds supprisingly accurate a few times, then got a little brave and tried an 80grn. load out to 40yds again quite safely with not catastrophic failure of course (obviously since i'm using both hands to type). I have read very little on any thread about powder charges in almost any .45 cal rifle, yet alone a kentucky style. I know that .50 to .58 are the most popular of any style of BP firearm, I'm sure leading to the small ammount of information on the .45 cal. I plan on using this rifle primarily for BP deer season where I live, however it would be nice to know the safe limits of powder charge for some fun target practice at a long distance range.
I appreciate any input any of you can give on this matter. And cant wait to read and learn more about my rifle.
