A round crab pot provides crabs easy access from all directions, while strongly discouraging exit except by crabs of nonallowable small size. The pot may be of variable weight and size for commercial or individual use. The pot frame has an interchangeable top and bottom kept parallel by perpendicula
A round crab pot provides crabs easy access from all directions, while strongly discouraging exit except by crabs of nonallowable small size. The pot may be of variable weight and size for commercial or individual use. The pot frame has an interchangeable top and bottom kept parallel by perpendicular supporting posts. The pot entrance occupies the entire height and circumference. The entrance is formed by a plurality of elongated spring steel rods connected to the top and/or bottom of the frame. The rods are positioned to slant inwardly toward the center of the pot and are connected by spring steel wire and a thin plastic medium. Thus, the entrance exhibits a spring-like tension as crabs enter. In a first variation, the rods are connected to only one end of the frame. Crabs may enter at ground level with the rods extending from the top of the pot, slanting inward and downward toward the center. By reversing the top and bottom, crabs may enter by walking up the rods. Rods of a lesser length may be attached to both the top and bottom of the pot. Crabs walk up the rods to the midpoint of the height of the pot and drop into the center. In both variations, the rods will not allow the crabs to exit.

A short-action firearm having an elongate chamber and bolt assembly comprising a tubular chamber and a bolt, selectively slidable longitudinally in a sliding direction between a retracted unlocked position and an extended locked position, said bolt providing a locked bolt face when said bolt is in said locked position, said chamber having a first end adjacent to said locked bolt face and a second end defined by a case mouth recess sized for operably receiving a cartridge with a projectile of a specific caliber within a range from 0.224 to 0.458 caliber, said chamber being capable of withstanding internal gas pressures of at least about 65,000 psi and being sized to matingly engage said cartridge so as to enable said cartridge to fire in said chamber with sufficient propellant to produce an internal gas pressure of at least 50,000 psi and to operably withstand said pressure, said bolt being capable of inserting said cartridge into said chamber and operably extracting said cartridge manually therefrom after firing of said cartridge at said pressure, said chamber having a first portion of substantially cylindrical shape adjacent to said first end and a second portion of a narrower substantially cylindrical shape adjacent to said second end, and a frusto-conical shoulder portion interconnecting said first portion and said second portion, said chamber having an overall length measured from said locked bolt face to said second end of said chamber, said first portion having an inner chamber diameter at a location 1.25 inch from said locked bolt face of at least 0.53 inch, said overall length having a ratio to said inner chamber diameter at said location of no more than about 4.2, said first portion having a first portion length extending between said locked bolt face and said frusto-conical shoulder portion, said first portion length having a ratio to said inner chamber diameter at said location of no more than about 3.33, said chamber being sized for operably receiving a cartridge free of any protrusion on said cartridge extending radially outwardly beyond said cylindrical shape of said first portion of said chamber, said bolt having an extractor sized for operably engaging said cartridge within an annular groove thereof capable of withstanding permanent deformation of said groove longitudinally of said chamber at said internal gas pressure of at least 50,000 psi, said firearm including said cartridge cooperatively engaged with said chamber for firing. 11. The firearm of claim 10, said frusto-conical shoulder portion extending at an angle of less than 40° with respect to a longitudinal axis of said chamber. 12. The firearm of claim 11, said shoulder portion extending at an angle of at least 30° with respect to said longitudinal axis. 13. The firearm of claim 10, said frusto-conical shoulder portion extending at an angle of about 35° with respect to a longitudinal axis of said chamber. 14. The firearm of claim 10 wherein
