Before you get too worried about which one to use, you really need to see which one will shoot the best out of your rifle. I suggest getting a couple boxes of them and a good supply of powder and spending a couple days on the range.

When I work up a bullet, I seldom take a second unknown bullet to the range with me. I like to have an unknown and one that I am sure of with its accuracy. It helps sooth my hurt feelings when I can't make the unknown one shoot well....

Good luck with your rifle.
