Now before a mod. jumps on this, this is a question for the experienced BR Shooters so I didn't put it in optics.

I am in the build process and am looking for thoughts and/or suggestions on the scope.
What do you feel is better fixed or variable. Up to what power this is for 100-200 yard IBS score matches.Now I have 61 year old eyes that don't see or focus like they used to, so more is probably better.
Would like to stay under $500. Unless I start selling some guns, but I doubt that will happen.
