Both Berry's and Rainier rate there plated handgun bullets for 1200 fps. MV. Don't be afraid to push them up over 1000 fps. you want have any problems. I love them in my Ruger 357/9mm convertible revolver in my 9mm reloads.
That what I get for have one too many!
Meant to say treat them as cast; not ass cast; but that does have a cool ring to it.
