Don't know how much help I can be, but I have a 26 inch, varmint contour, CBI, 1:8 223AI. I think that it will really be a shooter, much better than I can hold. I only worked with one bullet, 69gr SMK before I put it away for deer season, and I haven't even been to the range this year. I have a 3 year old and he gets all my free time now, I figure I can do plenty of shooting when he realizes dad really isn't that cool. That old rifle will sit in the safe and wait on me, but these days are going by way too fast. Here are a couple of groups from load development. I don't know about velocity, I don't own a chrono yet.
