hi. no stove piping. empty casing ejects fine. properly ignited casing have the indentation from the fireing pin on the rim. misfires...casings have a small flattening at the very edge of the rim, barely noticeable. I cant get 3 straight to properly fire from clip. ive exchanged clips, and ive went through a dozen different brands of NON bulk ammo. ive fired over 400 rounds. gun is well cleaned and oiled. excess oil wiped down. can anyone diagnose problem. my guess is the bolt. when I slowly extrude after misfire, sometimes the bullet is in the chamber, sometimes its pulled out attached to bolt, sometimes its half in chamber (I suspect the bolt is just letting go of it as I pull out). my guess is firing pin or inability of bolt to properly chamber? maybe its the clip release and theirs a bit of play. as for the firing pin, it seems to strike to low when it misfires. when taking the bolt out of rifle, I can move the pin up and down by pressing on top. should it be springy. mine seems to stick up and the I push it and it snaps down. spring? im from Canada and unfortunately I have to send it to an independent in Quebec and they are telling me to kiss my firearm good by for 8 months (repair). any help would be appreciated. I seem to be getting the same answers....ammo, dirty....break in....etc. thanks.
