Rob, what I meant by full power was standard 3 1/4 dram equivalent loads or greater, as used in standard field loads. By full power I didn't mean to imply Max loads of 4+ dram equivalents as used in the hottest buck loadings, which as you correctly state would not leave much quail to eat for dinner!
In other words, full power meaning 45 ACP ball, not necessarily 45 +P+ loaded to 225 power factor. The dealer said that the 1100 would not function with the light 2 1/2 and 2 3/4 dram trap/skeet loads, but with 2 3/4", 3 1/4 dram loads or higher, it would work 100% reliably. Is this not true?
