No, I wasn't being a smart ass about anything. Holding a rifle tighter will increase the load's muzzle velocity. And case neck friction changes will also change it.
Glad to hear you're shooting the rifle free-recoil. Most folks don't realize how much the way they inconsistantly hold a rifle reduces its accuracy. And if you're group shooting, free recoil (or a proper machine rest) does indeed produce the smallest groups.
Sorry I mistook your scientific responses for humor.
IBS Varmint Hunter class matches are all score matches. Front rest ie. Hart, Bald Eagle, Farley and others are allowed but no mechanical rear rests of any kind.
In your opinion how much of a velocity gain would one expect to realize by holding the rifle tighter?
