Free: Contests & Raffles.
Your gun has a small chamber at the breech area and the powder has to filter and settle into this chamber for the fire from your cap to set it off. Before shooting or loading for the range or hunting try running a 91% alcohol patch down the bore, followed by a dry patch. Also take the nipple out and clean the flash channel. Now let the alcohol evaporate and leave a clean dry oil free barrel. Before putting the nipple back on blow some air down the barrel. You should be able to hear it exiting the drum where the nipple goes. If you hear moisture then things are not dry yet. My lyman rifle is similar to yours and the powder chamber in the breech is I think a 38cal. I use a 38 pistol brush to clean down in side it. Before loading you can still pop a cap or two just to make sure the flash channel is nice and clear/dry. What powder are you using? 3f may be better than 2f it will settle down in the breech better. I also give my rifle several good slaps on the side of the lock area to settle the powder and get it started toward the drum/cap. Muzzle loaders are like women..gotta treat um right. OH Ya I Agree with the other poster from above...with that tag why are we waiting till now to work out the bugs..buy ammo..think about new rifles etc. Good Luck on killing a nice bull.
