Check out
www.prbullet.com you will find the Traditions bullet (Silver Lightning) and the Cabella' s bullet (QT Polymer Tip) there. They make them and provide valuable info for ML' s also.
Almost forgot, I have also used the 250 gr MZ' s. Great performance on two bucks in the 2001 season, used 303 gr JHP Rem Core-Lokts in 2002 also on two. Both bullets performed well. I had no problem using the MZ' s in my 2001 Austin & Halleck .50 cal, didn' t have enough MZ' s to work up a load in my new 2002 Austin & Halleck .50 cal. Two other friends use MZ' s (300 gr) in their A&H ML' s with no problem.
