I picked some up a while back to shoot in my 280 Sherman. They are indeed a VERY long, streamlined bullet and have a smaller meplat and longer boat tail than a 180 Berger. My initial tests did not show the accuracy (at 100 yds.) that the Berger did but that was with only one powder. I am going to retest them with a case full of RL33 and see what happens. My initial test was with RL26 and I shot some at over 3100'. The accuracy was at about .6-.7 moa at 3000' but the Bergers shot .2 moa. I have a 9 twist barrel, and sierra calls for an 8, but I don't think that is the problem because I was shooting at 4500'. My goal was to get them to group well at 100 and then back off to 1000. I was then going to do some expansion tests at various velocities. My gut feeling is that they might have some SERIOUS long range hunting potential. Given the angle of entry of the nose of the bullet being even greater than a berger, the hollow in the nose being about the same, and the thin jacket, I feel that they may expand well. They SHOULD act similar to a berger as far as penetrating a couple inches before they expand. They do have a little smaller meplat which may slow expansion somewhat, but the angle of entry may offset that. Only field testing will tell? If I can get them to group, I will try to do some expansion tests later........Rich
