http://www.shotgun-insight.com/fibreVsPlasticSporterShells.html"…the patterns over the 9-shell average are almost identical. The distribution of pellets in the 10", 10-20" and 20-30" areas are almost identical. Similarly the probability if hitting the small area of an edge on clay is almost identical."
"What this means is that there is no evidence of the fibre wad shells having inferior patterns. This includes any effects of the wad affecting the centre of the pattern or shot deformation leading to more fliers."
re: pressures. Fiber wad shells tend to be slightly lower
