that 410 of yours will do great on everything from bobwhites up to pheasant. you have to be fast with pheasant though, no 25 yard hail mary's with pheasant.
i use mine on bobwhite hunts with my dad in florida and up here in new york on grouse, etc.
for some reason crazy reason, i like the 410. i just feel real good about taking birds clean with a 1/2oz of 8's. my thing is that if you can't hit them with a 1/2 oz will you with 1 1/8 oz ?
if you use your sb1 for birds, practice with skeet singles or sporting clays shooting low gun, i do just that in the off-months at least once a week. sharpen up for fall !!!! i can't wait !!!
