Ahhh,
The problem as I see it is that with the "fashion" for short actions and the loud vocalistations by the small minority who advocate such things, have convinced the scope makers that short tubes are best
. I like classic rifles and a lot of them have longer actions and hence wider spacing for the scope mounts which is one reason I like the Pecar Berlin scopes as they have long tube bodies. Unfortuneatly they are expensive new so I have to shop around for good used ones. The Schmidt & Bender scopes (I have a 6x42 one) also seem to have plenty of tube length ofr mountign and getting the position just right. Again they are expensive
as are Meopta another one with good tube length, I picked up a used 7x50A.
Sorry to say but I cannot compare my American made scopes as three of them have straight front tubes being :-
Weaver K3W (steel)
Weaver K1.5 (steel)
Bushnell Scope Chief 3x ( appears to be a brass tube?)
The two Leupolds are a M8 Compact 4X and a Vari X111 2.5-8X so both are shortish scopes. The VariX111 is fitted to my P-H 1200 Super in Leupold QR lever mounts. The rifle has a LOP of 13 3/4" and the eyepiece is 12 3/8" from the butt pad. This works fine for me and on 8X when I lift the rifle to my shoulder I get a full field of view. Of course the P-H 1200 uses a Mauser 98 action so it's fairly long but these mount work fine on this rifle.
