It's no secret that Ruger's proprietary cartridges are not doing well. If you have watched Ruger's history they never give a hint they are going to drop a particular cartridge or fire arm model . They just do it with out notification. When Ruger was asked if they would bring out the PCR they stated no. We have had cartridges like 6.5 Rem mag, 6.5x284 all started with a lot of fan fare & then slowly go away. One thought I had for those with own a Gap or PRC was that since they had a mag base maybe the rifle could be re chambered to a 6.5x270WSM. At least there is a good supply of affordable brass new & once fired. Also the cartridge is fairly popular which means a supply of brass into the future. I would recommend to those that have rifles chambered for the Gap or PRC to get in a good supply of brass. One day it's production will just stop. I base this on what history has taught on such cartridges.
