Hm, a split forcing cone is not something I'm going to risk. I'll stick to FA JFP.
I only asked because I noticed that the teeth at the end of the Gold Dot's jacket are folded back into the hp's cavity, so I thought that might help prevent shedded jackets.
Thanks for the warning; I never realized the cone might be at risk with soft core jacketed bullets. This is because the hp might begin to expand upon jumping the cylinder gap, correct?
