I recently bought some bullets from Hornady, for the .357 magnum. After having accuracy problems with my 180 grain RF cast bullet, I decided that maybe it was time to invest in some good jacketed bullets and see if I could get my Marlin 1894 to group with them. I ordered one box each of the Hornady XTP bullets, one billed as a hollow point, the other as a flat point, if the FP designation is to be believed.
They appear to be standard cup-and-core bullets with flat bases, however I'm a bit intrigued at what Hornady is calling a FP bullet.
I haven't loaded jacketed bullets in the .357 in well over a decade. It'll be interesting to see how this experiment comes out.
