I don't know if this is the right forum for this question. Also, I think I remember sometime last year the subject of Semi-wadcutters came up. But, I can't find it. I am looking at buy some bulk ammo. They have the .38 Special 158gr Plated Semi-Wadcutter and the .38 Special 158 gr Full Metal Jacketed rounds. What is the benefit or difference of these two? Also, consider that they are both +P, if that matters, Wanna kill these ads? We can help!
