Thanks to Alex C. at TheFirearmBlog, I recently had an opportunity to do some shooting with a .276 caliber Vickers-Pedersen model PB rifle. This was one of the very first rifles Vickers built when they though the Pedersen would be adopted by the US military and couple be further marketed worldwide - after only about 16 PB rifles they made some changes and started making the improved PA model instead (the two main improvements being the use of a reversible clip and the addition of a mechanism to allow ejection of a partially-full clip). Anyway, in addition to Alex and myself, we were joined by Nathaniel F (a TFB writer) and Patrick R (from the TFBTV video channel). Between us we put about 60 rounds of original 1920s wax-lubricated Frankfort Arsenal .276 Pedersen ammo through the rifle.
