1964 g and a mag, 600 ft lb load, 9mm

achieved by hollowbasing regular 9mm ball bullets. I read it in 1966, I was 14, so no, I dont recall the details. I woiuld have had no idea what powder did what, or what grains meant, etc. But I DO recall being astonished that the load's power could be almost doubled with such a simple expedient. Of course, the ball bullet lets you make the base cavity a lot deeper than a jhp will allow. you can put the bullet in one drill, in a vise and hold another drill or dremel grinder up to the spinning bullet and make the base cavity. It's not rocket science. weigh it on your powder scale, repeat.

I remember one article in some gun magazine about casting bullets from zinc, rather than lead. It was a long time ago, early 80's or maybe late 70's probably. Never tried it.

zinc is toxic, Ayoob did one about casting with tin. He was unaware, tho of the hollowbasing trick. He got a 140 gr swc (200 gr mould) to 1400 in the .45. Some guys claim safe 1800 fps with 185's in the .460 Rowland. first one is easy, second is insane
