I have hated my T/C Encore Muzzleloader ever since the first day a shot it. Its only been a couple of years and I have read many posts on this sight and tried a bunch of different suggestions. Today I recieved my first 10 oz bottle of BlackHorn 209. Alls I can say is WOW. Great stuff. New scope 2 weeks ago shot a few times100gr777and quit. Today after bore sight 2 shots @ 30yds with slight adjustment and 2 @ 75yds 1.5" high with slight adjust and in the bull. No patching 4 shots easy loading and clean group. Its the first time for me with a muzzleloader that each time I made a click on the scope the bullet moved accordingly. Thank you very much for all the info on this sight. Now I am going to clean it with som Hoppes #9 which sounds like it is okay to use. Any cleaning tips would be helpfull. I dont think with BK 209 any of the T/C cleaners work?
