I have an odd problem with my R93, and need some help. The bolt has become progressively harder to close all the way on my R93 Professional (6.5×284 if that matters). If I close it normally, the firing pin will fall, but it is enough out of battery that it fails to fire. I really need to push the bolt handle forward forcefully for that last “click”.
How do I service that? Is it something I can do, or should I send it to Blaser USA for service? Or is this the final sign that I really need to upgrade to the new model?
Sounds like your ammo was not full length resized. It can be a real problem with new Lapua brass, I once had 200 cases I had to pull the bullets from and resize, after thinking all I needed to do was resize the necks of the virgin brass in my 6.5×55.
Try it with some factory produced loads and see if that matters.
