If you are still after a Spuhr mount, Mile High Shooting was real helpful when I contacted them. Great folks to talk to and helpful. They are as their name indicates out of Colorado.
I use a product called Nu-View. I bought it at one of the sports shows here in Michigan. It works good as an anti-fog and it fills minor scratches. Seems the more I use it the better job it does. A little goes a long ways.
Wally - I'm in Milford, MI. Windshield time is not a problem for me. I drive quite a bit for work, and fish the Great Lakes (Michigan, Erie and Ontario) frequently. Nice to meet you.
Just want to drop in and say HI! I'm just getting into long range shooting, past 300+ yards. I'm looking forward to learning and passing on what ever knowledge I can.
