I understand that perfectly the ballistics are the same ,my idea was to have the 2 scopes start out at approx. the same settings,so I was thinking the one on the tobr with 0 moa would need be set higher to begin with.as in the exposed numbers on the scope dials(but would be close to the same with a 20moa mount).i realize that makes no difference as the scope doesn't care where it's zero point starts and from there it is all ballistics. but if possible I'd like the two scopes to start out around the same number of clicks up.
besides is there any reason not to have a 20 moa base? especially for guns I'm planning on shooting out to 1200 yards with. maybe the lt745 is what I seek.
