I used a Blaser R93 for several years in 300 Win Mag, 338 Win Mag and 375 H&H. Then I got spooked by reading a couple of articles on bolt failures that resulted in horendous facial injuries to the shooter. When I took a closer look at the bolt and locking mechanism design I decided to divest of the kit a few years back.
I transitioned to an HS Precision LA2000 Takedown Set in 300 RUM & 375 RUM. I picked it up second hand in near perfect condition and took it to Cameroon for Lord Derby Eland and ancillary plains game. Earlier this year I picked up a second one in 300 & 375 H&H. It was a classic weak moment and good price so I jumped on it - figured one of my kids will use it!
Finally pulled the trigger on the kit I've been looking at for several years now - Dakota Traveler in 338 Lapua and 416 Rigby a very well done set. The original owner ordered upgraded wood, leather covered recoil pad, express sights and hooded/banded front sights, topped with Schmidt Bender glass and two hard cases. Sadly, he never got to hunt with the rifle so it was a safe queen for 9 years. I'm taking it to Uganda next year for its "coming out". Pictures and report will follow April 2018.
I've got complete confidence in either of these rifles locking up solid with no risk of bolt failure.
