Jim, thanks for the response and clarification. That was my thoughts on the 162/165 but wanted to bounce the question off of yall.
A very good example of the variations of the same bullet that may be referenced as a single bullet in the MM are the RBTRF IV Bullets 241 through 245 (MM-453 Sharpshooter). All are the same bullet (except 242) and show variations in sizes and charateristics associated to one bullet.
Jim, not JA3R, the 241-245 are fantastic CS 3 Ringers
