Straight-wall pistol-caliber rifles are not permitted north of the C&D Canal.
Delaware Hunting Laws
Delaware allows rifles for deer only in a narrow slice: handgun-usable straight-wall cartridges (.357–.38 with a 1.25"–1.82" case, or .41–.50 with a case up to 1.82"), capped at 3 rounds, usable only in place of a shotgun or handgun in those seasons — and not at all north of the C&D Canal.

Sources & methodology
Rules on this page are verified against state statutes, administrative code, official agency regulation digests, and federal regulations — never forums, retailer blogs, or hunter-ed course summaries. Rules we could not yet pin to a primary source are labeled needs review and never produce a green "legal" answer. Cartridge energy figures used by the checker are typical factory-load values; where a rule sets an energy or bullet-weight floor, verify your specific load's manufacturer rating.
