There's always something, Grrr.Having accuracy issues with my 350 Mag I took the gun apart, yet again.I noticed the yoke under the receiver that the front stock screws go into (see pic) is loose: it can be rocked side to side for about 1mm total travel. It's obvious movement here can wreck accuracy, as the irons have a chance to move during the shot sequence, even when the stock (and the shooter) didn't. 1mm movement here projects out to several mm's at the muzzle, to maybe inches at the target...Let me wonder what Diana engineers were thinking, joining the yoke into the receiver by a SCREW, in a magnum springer known for its powerful recoil? Sure, the screw head has been struck (twice) by a punch at the factory, but it just cannot suffice to make the joint magnum-proof. There's a reason other manufacturers weld this joint. Unscrewing the yoke screw revealed a machine-oil soaked mating surface, lightly ribbed for extra friction. The yoke itself is dovetailed into the receiver bottom, and doesn't want to come off (not that I really tried, seeing no reason to risk it). I reckon cleaning, Loctiting etc., possibly re-punching are in order here, but let's hear if you have had the same issue and how you dealt with it.
