Any suggestions for new scope for Rigby .275? Rings being made to fit the original Rigby mounting system. I can go with either 30mm or 1 inch but leaning towards 30mm. My biggest question is 42mm objective or 24mm objective. I mainly hunt whitetail in the South East but will be going Red Stag hunting in Scotland next year and eventually a Safari. Looking at 1X - 6X or 2.5X to 10X. Advice and thoughts appreciated. Thank you.
