David - that's some pretty good shooting. I have also gotten very good groups at 200 yards with the 250 Shockwaves - pretty consistent 4 to 5 inches with the 130 gr. Pyrodex pellet load.

Did you notice any difference in recoil between T7 and BM3? It is my understanding that 100 gr. of BM3 is the equal, in terms of velocity, to 120 gr. of T7 or 150 gr. of Pyrodex. I'm still trying to get my hands on some without coughing up the hazmat charge.

By early next week, I hope to have a terminal report on the 250 Shockwave. We are going to the ranch in New Mexico over the weekend to try and fill some cow elk tags.
