"Mule,tryed lots of different loads and about 1 1/2'is the best she would do.Iv'e gotten into lond distance deer hunting and want to reach out 300 to 600 yds. Iv'e got a .243 that will shoot 1 1/8" @ 200yds but, it's sarting to run out of punch past about 350 yds . Maybe a stock would help but, I've heard it doesn't always help a sportster barrel to be bedded and free floated.
