Reviews I've read using neighborhood 100 grains of powder have been good for the PT Gold holding up. One of my top-3 best economical copper-clad bullets out there, when purchased in bulk. Harvester people have mentioned a possibility of a 200 gr 40-cal version coming for 50-cal rifles, but it's still missing from their lineup card.
That's the one I'm waiting for. Much like the Shockwave/SST, I feel the best of the bunch is the 200 gr version. Less complaints on that smaller one, versus the SST/Shockwavwe 250-300 grains.
