First time posting here, but long time lurker.
Howdy gents, have an old project that needs finishing. It started life as an Interarms mark X in 25-06 and was rechambered to 257 WBY. (I’m guessing on the 25-06 part)
This was all done prior to me and likely done sometime in 80s as the import date and the scope are both from that time. Rifle feeds property and extracts strong, shoots well, however it doesn’t eject brass worth a darn. I’ll do my best to describe what I’ve noticed.
(Bolt to rear) When the brass makes contact with the ejector it pivots the brass over into the rear receiver. The brass is then ‘flung out’ of the bolt face, with the case head making contact with inside of the receiver, this pivoting the case back into the mag well. I shot some slow motion video, although I’m not internet literate enough to post a video of what’s happening. So we have my notes above.
Few thoughts.
1: ejector is too short, although it protrudes through bolt face when bolt all the way rear.
2. Rear bridge needs milled to allow case to pivot more, before being kicked out of bolt face
3. Extractor might be a little tight. How many thousandths should extractor be displaced by ‘grabbing the case head?
Thanks in advance. My apologies on typos and details. Posting from a phone.
