I would go higher mounts. If you push your zero range out further on low mounts you will have a high zenith i.e. with a 35 yard zero you are +0.6 mil-dot at 15 to 25 yards

Having said that, a 32 yard zero with your current set up may work for you. 1st mil-dot is at 45 yards.

Make the effort with Chairgun - it is well worth it
