I used them two seasons ago. They are the most accurate bullet I have ever shot out of my rifle (.270). However, I did not really are of them when it came to knock down power and meat damage. I literaly blew a doe's head off when I shot her in the neck. It cut her whole neck in 1/2.

JMO- If I were shooting a .243 for deer, I would want a bonded bullet. My uncle shoots Cor-Lockt and he loves them. However, he did loose a monster a few years back. JMO- I would go with a 308 over a 243 for deer.
