So, why would CVA limit sabot size? I'm not saying the manual doesn't say that, but your theory on the skirt on a PB blowing is flawed.
Yes Pete, a sabot is a safety valve as well. But a bullet and sabot is a hell of a lot tighter then a powerbelt. A powerbelt doesn't get tight until the pressure under the gas check builds and makes the powerbelt obturate and engage the rifling leaving the bore. As far as I know, only lead bullets obturate. You take a Lehigh Brass bullet thats not happening at all. So the sabot blows and the gas leaks around the bullet.
