I have always admired the Sako rifles I finally decided to buy one. I chose the 85 Finnlight in a 270 wsm. I bought a Vortex razor 5x25x50. My first hunt with it was an antelope hunt.I shot one at 500 yds,confidence builder. This year my son and I went to Eastern Montana to harvest a trophy buck.My son spots a nice one at a ridiculous distance but he talks me into the journey.When we arrive the buck hides behind a tree.We waited a couple of hours and he steps out at 500 yards I have my opportunity.I fire and I miss,I reload I fire and click its a dud. I eject and the bolt falls apart.I put the parts in my pocket and my son kills the buck at 300 yards.What makes SAKO bolt come apart?
