Starline Brass Cases Cal.: 40-65

  • A.K.A 40-65 Win, 40-65 Winchester, .40-60 Marlin, .40-65 Marlin 
  • 2.097 - 2.104 O.A.L. 
  • This obsolete vintage cartridge was originally designed for use with both smokeless and black powder. Our case is properly sized to fit in even the tightest chambers*. Internal capacity is similar to that of Winchester brass. Wall thickness at mouth is .0095" average. *Note: In firearms with larger chambers, this brass may become shorter than desired after fire-forming. Those shooters who wish to have brass that is longer than 2.090" after fire forming and neck sizing should form our .45-70 brass into .40-65 as a good alternative.
