OJ, Blazer 230 gr ball from Natchez is FMJ, not TMJ. It may not be completely relevant to the discussion, but may be relevant for those thinking they are going to get really cheap TMJ .45 ammo from Natchez. They aren't.
FMJ and TMJ were of special concern at the indoor range where I shoot. TMJ puts a lot less lead in the atmosphere than FMJ. I originally bought the Blazer from Natchez because it was said to be TMJ. Bounce ball slugs from the backstop (in part, made of rubber conveyer belts) clearly showed no metal on the bases of the slugs. They are FMJ only. When I called about this is when I found out from the employee that the rounds were FMJ, not TMJ. So the information I shared with you was direct observation of the product, backed up by what the employee told me. Like I suggested, pull a slug for yourself and see.
In short, the information I received from the folks at Natchez was not in error, but their catalog is, and has been for quite some time.
I have just opened a case of Blazer ammo I got from Natchez. The boxes are clearly marked on the end as FMJ. The reference to TMJ on the back of the box is in reference to special 'Clean-Fire' ammo that they make as well. Only the Clean-Fire ammo is TMJ.
Currently, Natchez sells only one type of Blazer .45 230 gr round and it is FMJ, Natchez # CC3570
