This is what I have on hand for practice and home defense. (38 spcl) 148 WC my good friend loaded at about 750 and Remington 158 HTP plus P lead HP. When I first got the gun I loaded it with some 180 .357 Black Talons. I found out they are suitable for my 28-2 but not the M60, regardless of who is pulling the trigger. Lots of Win FMJ and a variety of 357, but no. I also have Hornady 110 +P FTX but that looks like it's more for tube fed carbines.

I'm leaning towards the Remington HTP. It looks a lot like a SWC but with a hollow point. It's time to get her and the 60 to the range. With the slight increase in mass, 2 1/8" full jug barrel, plus the RB targets, it should work. She is pretty good with hand guns but better with the M-16.
