Interesting. I have both the Town & Country "Junior" (model 110) and "Senior" (model 108) myself. My 110 is also the harder hitting of the two. I find myself shooting my 110 more often than my 108. It retains a little air when pumped 5 or more strokes. I use this to my advantage: after a few shots I am getting near 600 fps with 5 pumps, 640-650 with 6 pumps. This is with JSB 13.4 grain pellets. It had a pretty stiff trigger until I replaced the original spring with a lighter one. Both guns are quite accurate, the 110 a bit more so than the 108. I have scopes on both of mine. The 110 regularly groups 1/2" and less at 20 yards.
Went to Hardware store today and bought some springs after about 5 different combinations, lol the trigger is much nicer. Now to snag a weaver scope on the bay, just a Terry wantabe? Maybe some barn siding for the picture backdrop?
