They are full metal jacket. I will check on part number when I am home. I agree with you Skip on being extra careful and I am glad you are vigilant on reloading threads. For me personally, in the future I will probably PM somebody with info then they can get as much or as little as they need. I probably know more than some and a lot less than others (Skip, Rich, Denny). There is a lot of information that we are not mentioning; diameters, overall length, how far the bullet is seated, how deep the primer is seated, etc. Overall length for example along with how deep the bullet is seated can be a big issue on some loads, probably a lot more critical than the bullet being FMJ. Reloading can't be taking lightly. If I did not have a great mentor, I would not do it. JMO.
