RScott and Jason, thanks again for the suggestions. Checked out Hollands info as well as Sierra and JBM calculators. Played with the data input and printed a few cards and then collected hard data this afternoon. Amazing how close the soft data was to the hard data/range results. I was very suprised...and pleased with the results.
Elevation changes, temperature variations, and playing a bit with the wind (it was dead still today) are next on the agenda. Then another load, and then another caliber, and then......more fun!
Thanks again guys!
