most of speers bullets are thick plated ie golddot,tmj though do have a jacketed line and lead.
hornady likes to use short OAL for some reason. feel free to take the OAL out to 1.120-1.125 not sure where you will hit rifling take a bullet and case and find out. take a marker and color the bullet similar to the old smoking method check what OAL marks start appearing.
