In preparation for the return of my GP100, I bought another box of the 200 grain jacketed hollow point from Underwood. Today I shot some of this ammo through an old Taurus model 431.
Much to my surprise, this ammo keyholed like crazy out of the Taurus.
So at this point I think Underwood may have gotten some out of spec bullets from Speer or they may be pushing the 200 grain Gold Dot too fast to be properly stabilized by a 1x20 twist. At least with A3 inch barrel.
This afternoon I called Underwood and spoke to Justin. I told him what I was seeing and that I had a couple different guns now that have keyholed with their hot Gold Dot ammo. Justin said he would do some research and call me back.
I guess one way or the other I'll get this figured out.
