I bought a BPI Connecticut Valley Arms MagBolt 150 Made in Spain 45 cal. 1:28 twist rifle with a Bushnell 3-9 power scope that has no markings other than "Bushnell. The scope looks cheap. The guys said he hunted with it one time missed the biggest buck of his life, it stood there until he reloaded and tried to get a primer in it twice. Just as he got the primer in the third time it ran off and he could not get a shot. He put it in his closet and it has been there ever since. I asked him if it was loaded and he could not remember. There is some heavy ruse on the end of the barrel and down in the barrel. How do I check to disarm it, try to shoot it? How do you get it apart to see if it can be cleaned out and how would you take care of the barrel if it is badly rusted, as I expect it is. Oh, by-the-way, I have never had a blackpowder rifle before. Was $50 too much to pay for a gun in this condition?
