I am looking to get started moving out past a set zero. I want to set up my 243 with a better scope with target or CDS turrets so I can dial out for long shots. This rifle was a gift from my father. Nothing fancy but the barrel is glass bedded and I have shot a number of .5 MOA groups at 100 yards and under 1 MOA at 200 yards. My question is will this scope mount work to reach out to much longer distances? See photos attached. Not sure what this type is called. It doesn't have slots cut in the rail like a picatinny. I am thinking a 1 inch tube diameter scope can just be dropped into this mount, if it is a good mount. Thanks in advance for your help.
