Not as bad as I thought - I suppose the extra velocity from that 11" barrel helps.  I took a couple of shots at 50, didn't see much difference.  I just took some estimates and plugged them into an on line ballistics calculator, looks like between 25 and 50 there's little change (maybe a quarter inch). With a 25 yd zero, the bullet will be rising above line of sight for a while so at 50 yds might coming back to line of sight.  I didn't take my chronograph out today, would be interesting to see how that velocity compares between a 5" and 11" tube.  The "Ballistics by the inch" website would lead me to believe it's only about 100FPS  faster, which is surprising.
One of God's greatest gifts to us is
the great outdoors - get out there
and enjoy it!
