Nomad,
Apparently, there have been several accidents with the R93 in Europe.
According to the
German Hunting Magazine, on January 10, 2004, 38 year old Albrecht Huf was critically injured when shooting a Blaser R93 in 300 Weatherby Magnum. The receiver exploded on the fifth shot and launched rearward underneath his eye through his cheek and came out under his jaw. His thumb was also fragmented. Not a good thing. According to the report, he was using original Weatherby ammunition. Here is the report in the magazine, albeit in German:
http://www.djz.de/artikelbeitrag/artikelbeitrag_26168.htmlA knowledgeable shooter, Lutz Moeller from Germany has been researching safety issues with Blaser rifles. Here's a link to his site where he answers some questions regarding the Blaser R93. He is not thrilled with the R93 construction.
http://home.snafu.de/l.moeller/Zylinderverschluss/Zylinderverschluss.htmI understand many don't read German, but you if you scroll down you will see a large sectional drawing of the R93 receiver which shows (in red) where in the event of a rupture, dangerous gases could lead to the effect described by you - i.e. the bolt and receiver becomes the projectile. Scroll further down and you will see a picture of Albrecht Huf and another unfortunate fellow, Jan Sorlie, from Norway, who lost his right eye and had part of his skull replaced with Titanium. Good thing these men are still alive.
Here's another link to the same magazine, dated 11/2000, regarding a recall of the Blaser R93:
http://www.deutsche-jagdzeitung.de/artikelbeitrag/artikelbeitrag_11127.htmlIf you scroll all the way down, you will see two pictures of a bolt assembly. The top one is from an actual accident, and the bottom one is from subsequent tests by Blaser. Similar results. Also at the bottom, is a picture of the exploded receiver during a test.
I would think that Blaser has addressed these issues, but I am not impressed with the security of the Blaser R93 design, and personally, I wouldn't own one.
