I was at a Central Pa. gundealer the other day, just to windowshop and pass some time. I decided to pickup a couple boxes of bullets for my 7mm WSM
. I got a box of 162 gr AMax in copper and one in Moly. When I went to check out, the owner, who seems to be knowledgeable, ask me if I was planning on shooting them both out of the same gun. I said, yes. He said I was asking for trouble. I said, how come? He said the copper will implant the Moly in the barrel to the point I would be unable to get it out of the barrel and mess it up for both. I said, How do you know this? He said, people at Hart told him. Wishing not to show my ignorance, I said give me two boxes of the copper.
Now, I am asking for your input. Facts based on experience is best, so if anyone has experience with this please let me know.
