I have been working on a new bullet for the big case 338 magnums, (It will be offered with my 338 Snipe-Tac loaded ammo). A specialty bullet for long range shooting, target version and a hunting (expanding) type. In no way am i tring to compete with the Sierra Match King, just am fiddling around with something different. The first prototype off the lathe for testing is a turned brass bullet, 1.995" long, driving bands, boat tailed. The weight ended up at 289 grains. I will experiment with a lighter bullet, in the 250-275grn range. With the driving bands the bearing surface has been reduced for less friction = increased speed. The bullet ogive is similar to the match king, only with a more slender tip. I will be testing different materials later on. This is a winter project with a friend who has purchased a Precision Hardinge Chucker Lathe, If all works out there might be other cal. bullets avalible.
Testing will start soon, groups and velocity.
Here are a few pics...
