QuickLoad would predict you are actually running faster than you have a right to expect:

Cartridge : .243 Win.
Bullet : 55, Nosler BalTip 24055
Cartridge O.A.L. 2.650 inch
Barrel Length : 22.0 inch
Powder : Hodgdon VARGET

Code:

%Fill  Wt(gr)   V(fps)    P(psi)      %Burn
 89     41.0     3,333     43,928      94
 93     43.0     3,485     50,448      96
 97     45.0     3,635     57,904      97

You've already lost ~90-95fps from the 2-inch shorter barrel, though you might pick up another 75fps using RL-17. But you're really not doing too badly now for the cartridge & barrel length.

(Low Temp probably cost you 20-25fps as well -- even if Varget advertises itself as temp-insensitive. Run a mag primer just for the heck of it.)
