I've got a pre-T3 Tikka called the "Whitetail" or model 595. The rifle is accurate but has always had a feeding problem. The magazine will feed OK if held tightly into the receiver. However, if its not held in, it will relax downward a fraction of an inch which allows the bolt to slip off the case head and ride over the body. There is a tiny spring loaded plunger that the magazine pushes upward when it is inserted. This plunger is always applying some downward pressure to the magazine flange and may be part of the reason that the magazine sits out a bit. How can the problem be eliminated? What does the plunger actually do when it is pused in by the insertion of the magazine?
