having trouble finding choke tubes that will fit mossy 535. if the package reads 500, will it fit a 535? barrels are not compatable from what i have read. contacted mossberg but all they said was to use their tubes. understandable but not much help. mossberg has accu-choke and x factor i believe. xx turkey choke is too tight for my shots! (.670) last 3 birds were killed by heart attack! must be because only a few pellets killed them! should be blowing their heads to pieces with 3.5 shells at close range. i know that choke is too tight at close range but thems the breaks, i am not gonna let them walk farther away am i? any combos that work for you? thanks. remember: dont hunt turkey for sport : hunt them for revenge!!!! ya, i know. a better aimed shot would blow their heads off, i know, i know, i know. thanks.
