well my thoughts here would be a dangerous game firearm... & or hunting of large game...
I found that Remington offers the SP-10 as an auto, in a turkey configuration with a shorter barrel & rifle sights, & a thumbhole stock... I'm not sure of the choke, & if it's conductive to rifled slugs, & or even if rifled slugs are available...
for this type of gun's use, a bolt action would be perfect... as a plus, a rifled barrel would be nice, as a guy could cast a harder slug if needed... mmmm... a Barns copper 10 gauge slug ???
sounds hard on the shoulder already...
curious as to whats out there ( wouldn't want to reinvent the wheel ), & what could be done legally with in ATF rules
