i have this gun in the old target version, i think it used the same barrel. ive since replaced the barrel. but my son won 10th ( nmlra kids contest ) in the nation when he was 10 with this same type gun with peep sights.. he used a bout 50 grns 2f and 490 ball and tc lubed patches.. but the best load will be 490 hornady ball (more consistent than speer), .015 patch, pure neatsfoot oil on patch, store will tellyou what caps to use.. even pressue on the powder is what its all about, and wipe between shots with a 45 cal nylon bursh and patch with and a little neatsfoot oil, if that dont work use a mixture of water and murphey soap oil ..small amounts... imp.... the problem is if you get any wet powder in the breache it will clog up the nipple and cause firing problems.. so to get accuracy you need to wipe, and this caouses misfires.. a unkle mikes nipple with a hole in it will help.. you should get two to three shots before problems arise, so it should be fine.. yes use a short starter, you can put gun on a scale when starting to load and press down about 40 pounds.. you can try other weigjhts amounts of powder betwween 65 and 90 grains, i would use 2f.. you can clean the bore after it is loaaded (no cap) and some target shooters do this, .. get pure neets fool oil for all your patches or use bear oil, it is the best,, i can argu and explain and go into it for a page or so, but try it and learn how to make it work,, good luck dave..
