I've had great luck loading the 58 Vmax in several different .243's. Excellent accuracy, great velocity, very flat trajectory, big time graphic terminal effect on p-dogs.
For p-dogs with a .243, I prefer either the 58 Vmax or the 55 B-tip, whichever one the particular rifle shoots best.
Have not run into a .243 that would not shoot one or the other as well as the rifle would shoot any other bullet. Have never had any problems with accuracy out to the ranges we typically shoot with them either.
I'm sure there are .243's out there that shoot well with heavier bullets but won't shoot well with these. Stuff like that happens with rifles. But, I have not run into a .243 like that, yet.
