I guess I just don't comprehend as well as most here. I opened the link but find nothing that refutes information contained in Larry's test? Actually I find information that confirms parts of the test, I know Larry's measured BC showed higher with the 10"( faster) twist than either slower twist, same as stated by Litz, and also believe they both agree that the faster twist increases spin drift. I would bet you that Larry also agrees that a 308 isn't artillery, I'll even chirp to that. I believe all this drama is just inflated egos flowing thru cyberspace and being egged on by **** stirrers. Too bad;( So for that reason I'm out of here. chirp
