i have shot around 100 rounds thru this gun with not issue until today been using w209 primers now they are indicting signs of high pressure getting stuck on the bolt face. this is the same load that I shot last weekend with no problems. been shooting 110 grains b209 all the time. anyways tried two different lots of ww209's and some federal 209a all the same results. i'm inclined to think that i have a problem with the bolt on the gun. you can see that they are bulging out and getting stuck on the bolt face
