I searched and saw someone else asked about these, but no one answered. Now that they have been around a while longer, maybe others have some experience with them. I loaded some up for my .223 and .22-250. I used the same load in the .223 as I do for the 40 gr V-Max or Ballistic Tip = 24.5 gr of H-322. In the .22-250, the load was a mid-level one with TAC. It ought to do about 3700 fps or so, but I will chrono it to be sure. I will try them on prairie dogs in AZ later this month.
Anyone used these yet? What load worked well? How did they work on prairie dogs or ground squirrels? A friend who owns a machine shop cut one in half, and they sure look like they would be pretty explosive.
