I am under the assumption that those Lehigh CF bullets are basically the same thing as the Bloodlines. I have seen those Bloodlines in action from my little sister and my dad. With this smokeless firebreather I would like to see how well it performs with sabots. In another thread Sabotloader posted a link to Lehigh and I ran across their .400 215 grain CF bullet. I also noted that they recommend 1:20 minimum twist rate for stabilization. This looks like a bullet I would really like to give a swing. Just wondering if any of you have tried it from your smokeless rigs or on an animal. Doing the math, making my head hurt in the process, I think I can get that bullet up to a little over 2700 feet per second without pressure problems. I do believe that would deliver a pretty decent amount of energy out to 300 yards on a deer or elk.
