I have a nice 1903 6.5 X 54 Carbine that came with two scopes, both claw mounted. The oldest is a Zeiss, the newer is a Kahles 4X. Both scopes have provisions for adjusting elevation only. I have read that these rifles were regulated with a certain load, and therefore, there was no provision for windage adjustment. Be that as it may, my rifle groups 2.5 inches to the right at 100 yards with the Kahles, the clearer and presumably newer scope. The group itself is acceptable. I am using 36 grains of RL-15 and the 155 Lapua.

It appears the front scope base is dovetailed in, but I haven't attempted to move it pending getting some advice. Can these scopes be adjusted in any manner for windage, or do I just have to remember to hold to the left? Would a different bullet weight work better?

I appreciate any help readers may be able to provide.
