Re: Tricks for keeping a .223 projectile straight
Set the bullet square on the case mouth, then keep your fingers in place on the bullet and the neck. As you raise the ram, keep your fingers there until the bullet is up in the die then pull them away.
In other words, when you pick up the bullet in your fingers and place the bullet in the case mouth, leave them there on the neck and bullet. Place the pair in the shell holder, then still leave them in place as you guide the pair up into the die when raising the ram.
I have the loading tray with the charged (with powder) cases next to the press then the bullet box left of that. I pick up the bullet, set it in the case mouth, then move the pair to the shell holder with my fingers covering the sides of the bullet and the case neck.
Having a good chamfer on the case mouth helps a lot too.
