I have the 2-7 prostaff on my 22 mag and it's a nice scope, but remember it's also set at 75 yds parallax, which works okay for my style of use. And may be good for your shooting also.
But for a 243 ya may want a 3-9 with 100yd parallax, they're not much more $ in the prodtaff line.
Nice glass for the money.
