You can use the tds reticle for any load. Check out the Swarovski ballistics calculator and it will give you approximate ranges for each subtension based on your load and magnification:

The rest of your post is unclear to me - it sounds like you have the ballistic turret model but someone replaced the factory asjustable turret with a custom one? If so, you can either go back to the factory one or have a new custom one made for your load. I believe there is a site-sponsor who makes them but for the life of me I can't think of them this morning . . .
