Re: .243 Win 87gr. V-max ?
My 6MM Remington pushed that bullet at 3300 fps using 43 grain of IMR 4350. My barrel is 10 twist Shilen Matchgrade and 28" long. I could probably push it a tad more, but I found my accuracy load at this velocity, so I left it at that. Approach your load with caution and pay attention for signs of higher pressure.
To achieve the maximum possible accuracy, all variables must be remove or at least minimize.
