Requesting details on Blaser breech block s2 double rifle
      #170104 - 24/10/10 05:23 AM

I have repeatedly looked, online, for detailed pictures with explanations of exactly how the Blaser S2 double rifle breech block fits together and functions, but have not been able to find much detail or explanation, only small pictures showing the action opened with breech block showing, but not showing much, and certainly not showing how it fits together and functions. I think that Merkel, and probably other makers too, on some of their models, use this same separate breech block system, that was originally developed prior to WWI by Jagaer of Germany. It allows for a substantially strong action to barrel fit up, able to withstand the highest of rifle breech pressures, even the .460 Weatherby caliber, since at least one German gunmaker made such rifles in this caliber, he wrote in Hatari Times magazine. Where can I find such good pictures/drawings and explanations of how that breech block fits into the cutouts in barrels and into the action, so I can understand the whole concept, which is quite radically different from other double rifle systems?

Thank you so much; now I understand how all the parts fit together, and how the whole thing functions; quite interesting it is. However, WITH ALL THE MOVING PARTS THAT OBVIOUSLY NEED TO FIT TOGETHER WITH QUITE CLOSE TOLERANCES, I WONDER ABOUT WEAR ON SUCH SLIDING SURFACES IN CRITICAL AREAS, WEAR THAT WILL LEAD TO INCREASED HEADSPACE MUCH FASTER THAN IN DESIGNS THAT HAVE NOT NEARLY AS MUCH SLIDING OF METAL SURFACES ON PARTS. DOES ANYONE ON THIS WEBSITE HAVE ENOUGH KNOWLEDGE AND UNDERSTANDING OF THIS SYSTEM, TO BE ABLE TO ANSWER THIS PARTICULAR CONCERN OF MINE?

I'd be very damn careful with a Blaser S2. I've owned two of them, 500/416 and 470. BOTH rifles broke in the first 10 rounds. One cracked at the wrist and the second cracked a forearm. Plus they both crossed at less than 20 yards. the 500/416 would not close on American ammo. It only shot WR!

In my humble opinion, these things were built by German guest workers from Guam. Buy a Searcy. I know Butch Searcy quite well. I've used his underlever .577 to take an elephant in Botswana. Plus, I'm not new at this. I write for hunting rags.

Nobody said that I was going to buy anything; only trying to learn something new.

They are inventive, and I doubt wear will be a factor in headspace. In the first place all parts are castings, and seem to be very hard material. I see that you are trying to learn here and that is commendable on your part. However part of learning is to listen to warnings as well. The poster who cautioned you about buying the Blaser was doing so from his experience with the rifle, and is to be commended for that warning. I think that usually someone who asks questions about a particular rifle in most cases are thinking about buying one, and I think that was his reason for the warning!

There is one other warning about the cocking system on the Blaser double rifle that needs posting for those who may not know! Many think the cocking system of the Blaser is the same as the Krieghoff double rifle and that is not the case.

When the Krieghoff double is broken open it cocks the rifle, then to make it safe after loading it the combi-cocking switch must be pushed slightly forward and released. This relieves the tumbler springs so the rifle can be carried fully loaded but can't fire. When the K-gun needs to be cocked the combi-cock switch is pushed forward(with some effort) to cock the springs. If the K-gun is fired and broken for a recharging of one or both barrels, the K-gun automatically re-cocks it's self so that when the rifle is closed on new ammo all that is required to fire the rifle is to pull the triggers.

The Blaser S2 double rifle automatically de-cocks the springs when the riles is broken open for any reason, and must be manually re-cocked before the rifle can be fired. This is not a good feature on the Blaser double rifle that may be used on dangerous game. If you fire one or both barrels on the Blaser, and re-load the rifle, when you close the rifle you better not forget to re-cock the rifle, especially in a very close encounter with something that wants to claw or gore you, because an un-cocked double rifle is not a rifle but a 12 pound club!

Warnings are not always for the poster they are quoting but for the benefit of all who may read the post! However, I hope the warning from me was something else you wanted to learn!
