Thanks for the kind words on the story. I'm afraid that my use of the English language and composition will keep me from having very much in print. I'm more of a technical person and the proper use of punctuation and such has never excited me (verifiable with any teacher I have ever had).
I was using a Bushnell rangefinder as was Brian, he had a compact 800 and I had the older 1000 I believe.
The rifle was a H-S Precision 2000LA and probably weighed in the neighborhood of 13 pounds. All my rifles are setup pretty much the same, I use a Turner Saddlery (military style) sling or nowadays a Tactical Intervention sling http://www.tacticalintervention.com/
and carry the rifle over the shoulder. I carry the rifle a little different than most folks; for a long hump I carry the rifle slung over my right shoulder and I hold some of the rifle weight by supporting the butt with my right hand (rifle on the rear of my body and the muzzle points over my left shoulder), for a short hump or when I may need the rifle in a hurry I carry the rifle slung over my left shoulder with the rifle on the front side of my body (my left hand cradles the rifle just above the trigger guard and I apply pressure to hold the rifle away from my body, the butt rests ontop of my belt which supports much of the weight of the rifle).
The horses did most of the carrying of the rifle during this hunt. Brian and I both needed to make custom leather scabbards for the rifles as the standard versions are far too small.
The ballistics program that I used during that hunt is the web based JBM http://internet.cybermesa.com/~jbm/
I had several data printouts and checked the data before departure for Colorado and once we arrived on site.
I now use an Excel spreadsheet that does a very good job. Peter Cronhelm's web site http://www.nucleus.com/~cronhelm/index.html
has the 'Sniper Ballistics Computer' spreadsheet available and I believe he'll have a newer version up soon, one that he and I have been working on for a while.
