title pretty much says it all. was selling with my S&B with horus reticle and buyer didnt need it. this software works with almost all palm models to my knowledge (you may want to check). you dont have to have a horus reticle to use it, you can use it with all scopes and reticles. it will tell you come ups in MOA or MIL, wind holds/adjustments in MOA or MIL, and hold overs in MOA or MIL. new this costs right at $200. yours for $120 shipped via USPS priority with insurance and delivery confirmation will trade for a set of badger ordnance medium height .885" 30MM rings that HAVE NOT been lapped.
