The RWS locdown mount is designed for the task. It has some droop built in. The droop in the mount isn't for drooping barrels, it is because of a high mounted scope on a short range rifle. If the barrel and scope are parallel, you can run out of adjustment winding the scope down to intersect the trajectory of the pellet at 10 yards.
I've always used the open sites on my .22 K98. I see 48's, 52's, 460's, etc. using droop mounts. Is that even necessary? They aren't break barrels.
