I have used 34 grain and 50 grain bullets. I find that they shoot well, maybe not as well as some of the premium plastic tipped bullet, but as well or better than some other spire point and hollow point bullets. With a 223 and the 50 grain bullets I was getting about 1.5" groups at 200 yards, but that was just some loads I threw together and really did not do any load development with them. I would really like the 34 grain bullets to do well in my 22 Hornets and 221 FB. With some W296 powder in the 22 Hornet, they get some outstanding velocities. I just have not worked with them enough to say that they are going to be "the load" or not.
