I have a recently acquired .223/20 ga. o/u. Shooting store bought .223 jacketed varmint rounds it was grouping 1/2" at 70 yds. Couple of days ago I tried my own cast .225 44 gr. boolits over 6,7,8 gr. of Unique. There was no trace of grouping, they were shooting all over the place at 25 yds. I thought it might be my boolits and still do somewhat. However, I may have found part or all of my problem.
Yesterday while running a patch through my barrel i found a very rough spot several inches from the chamber throat. I ended up scrubbing, wire brushing, using vinegar/h2o2 and hours of elbow grease to remove the accumulation of lead. After getting the lead out I still have a rough section of the bore about 3-4". I can't see it but I can feel it when I push a patch through. I have no clue as to why the barrel is rough. Perhaps a previous owner got something stuck and damaged the barrel trying to remove it. I am thinking if I shoot any more lead bullets I am going to end up with a heavy lead buildup again.
So now the question is ... what do I do about it??
