honestly in todays day and age, buck shot for deer is a piss poor idea IMO, its like poking and hoping, why not just use a slug, thats is tons more accurate and more lethal
if you were interested in maybe other models too, many come with two barrel sets, so you can swap a smooth bore longer barrel out for a shorther slug barrels, I know Mossberg and remington both off packages like this for fair prices and both guns are long time standing proven designs
thats my advice
a for suggestion on what shotgun to get, honestly the one that FITS you better will be your best for actually shooting it well(slugs can also be shot out a smooth bore with a improved cylinder choke too!
in many states too its Illegal to be carrying slugs or buck shot rounds ON YOU< while small game hunting, so read your hunting rules well before doing this, if this is your plan?
