At Century 200yd electronic yesterday. Fired 20 factory PPU 174 and 10 handload using 40g of n140 .
Everything went fine, nothing unusual, another great day shooting.
While cleaning my rifle I spun the bolt head a few turns . It felt gritty so I took it all the way off . It seems a small section of the thread has come away, see photo.
It was very tight to screw back on so I didn't force it . Instead I gently used a fine needle file to smooth the jagged thread. It screws on now but still dosent feel as smooth as it used to . The striker protrudes .046 ( when in fired position) and the gap between the cocking shoe and bolt body is .053 , about perfect.
Had anyone had a similar experience?
