Pendragon Galahad Buttoned Barrels are formed by drawing a precision tungsten carbide coated button through a drilled and reamed barrel blank. Selection of the correct lubricant is vital to prevent damage to the barrel and destruction of the tool. The operation is undertaken on a Unisig CNC controlled machine to ensure precise twist rates, which is somewhat more difficult to achieve on analogue machines.

​

Post rifling, it is imperative that buttoned barrels are put through a thorough stress relieving process which we do in-house to ensure it is done to our specification. Once stress relieved all barrels are hand-lapped for finish, and gauged for dimension and straightness.

​

Correctly done, a buttoned barrel is every bit as accurate as other barrels made by more traditional means. A Pendragon TVA Special buttoned barrel won the 2023 King's prize at Bisley, a remarkable feat given we understood it to be the only one of our barrels in the competition.
