Well I guess I have to go against the grain here, I have a two barrel set and when I put on the 26 barrels (they may have 4 boxes through them) I can't hit anything, put the 28 inch barrels (Mod/F) on I am good, so for grouse hunting I put a spreader in the full choke and a regular shell in the Mod, single trigger which I switch over to left barrel first with the spreader. But the 26" barrels are damn near new
