I recently purchased an 1860 New Army, fired it up during Memnoral Day, loved it. 1st question, I used Pyrodex powder and pellets, pellets are 30 grain but booklet calls for 28 grains if using loose powder. What is the difference between loose and pellets. 2nd, after my father passed aways he had some BP items one was a small container of 777, was never opened. My mom gave it to me knowing I am into this thing now..(was years ago too) but I noticed it was 2Fg not 3. It seemed to fire ok I used 24 grains on a few then 28 on a couple of rounds but it seemed to lack the "kick or power" of the pyrodex. Is it ok to use maybe just for plinking purposes? Anyway I'm hooked AGAIN and plan to add to the collection..
