Now that the weather is starting to moderate I will be doing some simple pattern testing with a couple long barreled tightly choked 16 gauge guns using fiber wads with Sprd R inserts and roll crimps. From what I have been able to garner from looking at various data from public and private sources it appears that chamber pressures are somewhat less with fiber wads while velocities are higher.
The load I intend to test is A Cheddite Paper Hull trimmed to 2 9/16th inches, 17.9 grains of Unique, 7/8th ounce of shot using 1/2 inch fiber wad with 1/8th inch nitro cards on either side of the fiber wad a Sprd R with 1/8th ounce of teh shot on top of the disc and .030 overshot card. My control load is a cheddite plastic hull, Gualandi 1621 wad with 17.9 grains of Unique and 7/8th ounces of shot. If anything interesting shows up I'll post again on Sunday.
Wyobirds I think for you to get any appreciable increase in pattern you will need to use some sort of spreder device weather it be a SpredR, X or soda straw
