Tell me what the FMFT stands for. Are they powder coated or copper plate?

That speed sounds real high for 4 gr of HP-38 which is the same as Winchester 231

According to Hogdon powder data 5 grains of 231 will yield 1100 fps. I push plated bullets all the time with 8 gr of Unique and Universal Clays. I dont have any issues
