Went to the range to try some lead bullets in a .357 that has never seen lead bullets. The first four groups were 4-5" at 25 yards. My revolvers will all shoot 1.5" groups at 25 yards. After four groups the fifth group was good at about 2.0" which is acceptable. I only loaded a box to see if I would get leading which was the purpose of running out to the range. This surprised me because the accuracy was terrible. The last few cylinder fulls grouped well. This is a new problem and would like to know if anybody else has run into this.
