I picked up two boxes of 50 230gr FMJ .45 ACP since WallyWorld did not have the WWB
About $15 bucks a box, it was worth a try.
I did not have a chance to try accuracy on paper, but the plinking accuracy was acceptable. Pop cans at 30 yards were challenging with a satisfying number of hits.
I would agree that they are a bit dirty, might even caused the return of the dirty extractor!
I don't see that these TulAmmo would hurt the kimber, and might recommend them to visiting shooters, if the WWB is not avail.
