What cartridge will you be shooting these in? Mine are 35 caliber and I am shooting them in a .358 Win. So with a 225 gr bullet I can only get them moving about 2400 fps. Even with the slow velocity, if the tip is right they open up with the perfect mushroom shape. You may not need to score them. Only one way to find out. Shoot them into something and recover them. We love looking at pictures of smashed up bullets!
