This'll save you more: stony point target knobs | eBay
These are marked in MOA. 15 MOA per revolution. I've used 'em for years on the same scope you have. Only made for Leups of that era--more or less. Can't find 'em anywhere but ebay anymore. For their cost, there's almost not excuse not to have them on the older Leups.
For the record, I think MOA knobs will be much more adaptable to a given situation that any knobs based on a certain load in certain environmental conditions. As soon as that new superpowder or bullet comes out or you find yourself in vastly different environmental conditions, unless the knobs are also graduated in MOA or mills, the knobs become much less useful. Get 'Shooter' on your phone for $10 and learn how to use it and have a much more adaptable, precise system.
