[QUOTE="Brown Dog, post: 59692, member: 1622"] Torsten, Glad you're having success with your R93 [img]/ubbthreads/images/graemlins/smile.gif[/img] Because of the peculiarity of the R93 bolt head (I can't think of any other design (except maybe the HK G3 etc series of assault rifles) that allows the bolt face to move back slightly whilst the round is fired. The critical length that changes (in the R93) is from case head to shoulder. It is this 'case head to shoulder' length increase that will cause the R93 (again, because of its unique locking system) to start to strike light. The OAL of the case is not the critical dimension to prevent this (ie trimming the case mouth will not address the problem). You will need to ensure that you 'bump' the case shoulder back to factory spec. Bottom line is to return your ammo to factory dimensions; if you just neck size, or fail to bump the shoulder when full length resizing, the R93 will start to light strike your ammo after 2 or 3 reloads Hope this makes sense! PS I'm a Brit! I've been to Finland a couple of times working near Rovaniemi at Rovajarvi (spelling?!) Had a great time. I seem to remember that Thursday nights were particularly hard on the liver [img]/ubbthreads/images/graemlins/smile.gif[/img]! [/QUOTE]
