I shot my 36 caliber flintlock blue ridge today. What a beautiful looking gun. I have about 300 rounds through it. Today I meticulously loaded to solve a problem with accuracy.I shoot .350 ball and .015 patch lubed with wonderlube. It feel smooth going down no snags and feels to have the correct resistance It will not start without a ball starter. I clean after every third shot. both sides of the wet patch followed by both sides of a dry patch.I use 1/3 peroxide 1/3 Murphys oil soap 1/3 alcohol to clean. The two ramrod pipe screws holding in the barrel are tight. I started with 15 grs of 2f goex 3 shots increased to 45 grains in 5 grain increments. Ignition is fast and consistant. Just about same group with all loads. 6" at 25 yards? sometimes vertical stringing sometimes horizontal stringing. At 40 grains I got a perfect triangle and about an 8" group. I went to 3F started the procedure all over again. Same deal 6" at 25 yards. I have a .45 and .58 cap lock and a .50 flintlock. As the grains increase on these guns the group gets smaller then eventually gets bigger. All three of these guns will shoot 1" and under at 25 yds. The .50 flintlock is one big hole with three shots. This .36 would be great for squirrel hunting. I am not allowed to use the .50 in PA with squirrels any more. I shot many a squirrel in the head with that gun. This is why I bought the .36 caliber. I have learned so much on this site. You guys are terrific. Can anybody figure this out and let me know what I am doing wrong. I hate to get a new barrel. This one seems OK and these guns now are out of sight with the cost. Thankyou
