Re: ? On bullets.
The only thing a would have any concern about is whether the bullet is designed to handle the load you are putting on it. Some bullets really aren't designed for all pressures and velocities so you could run into trouble. Examples are full pressure high powered rifle loads with lead bullets and super explosive varmint bullets in a 22-250 or swift; they may not play well all the time. You can sometimes run into issues like the 223 has where not all twist rates will handle bullets well also. If the bullet is a rifle type bullet and the diameter is correct have at it.
