Hello there Tikkaman, I hope this message gets to you before you attempt to crimp those bullets. Unless the bullet has a cannelure in it, you should not attempt to crimp them at all. Crimping a non-cannelured bullet will distort the bullet, and possibly skyrocket release pressures. Typically, the neck pressure alone, be sufficient for most shooting purposes. I dont recommend crimping that bullet at all. At best, velocitities are going to be eratic, and the bullet itself is not DESIGNED for a crimp. Pistol bullets are the more frequent for being crimped, and are usually equped with a cannelure for that purpose, and the reason that MOST rifle bullets are not, is because of un-known intended seating depth. Some rifle bullets are avail with cannelure, but usually with special purpose in mind, (ie30-30 bullets). Goodluck and BE CAREFUL. That rifle and the bullet you have chose are good ones and will reward you well. That bullet alone is one of the very best available at this time, and it will fly true, but DO NOT crimp it.
