Home Forums Hunting & Shooting Hunting Rifles Guess I drew short straw on a new Sako

I posted a video here a couple years back in comparison to a d'arcy echols rifle running through a full magazine box. It hung with the custom rifle at an impressive blinding speed without a single blip or hiccup, and the ejected cases had not a blemish. I'll need to search and find the video, but the pic below is of one of the cases from the video that was ejected from the 9.3x62 Sako. I've been running the same rifle since, and it continues to run top shelf.

Don't want to fiddle with mine because it is spot on, but thinking you should be able to increase or reduce the coil spring tension for the extractor claw for best function. Also, would think a bad batch of brass may cause an ill fit, especially if combined with a weak spring.
