On at 50, you'll be way high at 100. Think about it, your bullet is on a pretty sharp angle up to come from the bore to get dead on at 50, and that angle continues. At 100 it's still rising. Zero about 2" low at 25, get a tight group and then shoot it at 100. Don't shim anything.

My first thought is high scope mounts that are not level. The bullet only crosses line of site twice. If the mounts aren’t level and the front of the scope is elevated (pointing upwards) that could cause the issue I think.
