I have used the lipstick bullets but only in handguns. 9mm and .380ACP. No complaints other than they smell a little like burning plastic (no surprise). I was advised to use a Lyman M-Die (broken record anyone?) to avoid shaving any of the coating. I do and they load slicker than conventional lead. Light crimp, if any, again to keep the coating intact. I intend to try some rifle bullets one of these days...too many projects.
