Turkey tips ODNR

I'm new to the turkey stuff but the part about 12ga choke constrictions is somewhat misleading.Guns like Mossberg 835s and 935s are over-bored.Therefore what is considered a more open choke constriction in "normal" 12ga,would be considered tighter in a 835/935..I am not sure if this applies to very many makes or models of 12ga,but it does for the few I mentioned.I think the browning gold may be similar but I could be wrong.


(Side note).It took my dumbass about 5 years of owning before I realized a 10ga bore brush would be more beneficial to cleaning:smiley_boos:..I am gonna blame the owners manual for that one:smiley_depressive:
