I like the 100 yard zero as well. The only thing I did not like about my SWFA 1-4 is the hashes are set up for a 200 yard zero. I am still getting the feel of it but am leaning towards a 100 yard zero and then just confirming the drops for the rest of the marks.

Hunt hard, kill clean, waste nothing and offer no apologies.
