    Barrel press fit Pressing the barrel into the receiver to achieve a press fit is an alternative to using action threads which has been used on firearms such as Anschütz Fortner, Anschütz Model 54, [61] AKM [62] and Sauer 101. [63] [64] Barrel nut

  4. Overall length - Wikipedia

    en.wikipedia.org/wiki/Overall_length

    The overall length (OAL) of an ammunition cartridge is a measurement from the base of the brass shell casing to the tip of the bullet, seated into the brass casing. Cartridge overall length, or "COL", is important to safe functioning of reloads in firearms.

    While CUP and LUP numbers were intended to be comparable to the crushing power of a given pressure, the numbers are not equivalent. Since a longer duration, lower pressure pulse can crush the cylinder as much as a shorter duration, higher pressure pulse, CUP and LUP pressures frequently register lower than actual peak pressures (as measured by a transducer) by up to 20 %.
