Hi Guys,
I was out at the weekend with a group of friends, trying to trouble shoot a friend’s Blaser rifle.
For those of you who are unfamiliar with the Blaser design, it doesn’t feature a conventional receiver. Instead, the bolt mates directly to the barrel, and the scope mounts, mount directly to the barrel. In this case, he was using a scope with a rail system, so there weren’t ‘any rings to potentially cause problems. All in all, it’s a setup that avoids a number of areas were problems conventionally creep in.
He had noticed that he had experienced uncharacteristically poor shot placement on a couple of deer, and sure enough, testing on paper revealed that the rifle was shooting 4-6MOA at 100yds.
We tried a variety of different ammunition, none of which was any better.
We also tried removing the moderator (suppressor) and shooting with a naked barrel, but that didn‘t really make any difference.
Then we tried swapping scopes over, with a scope that was known to be good. Again, no better.
The bizarre thing is that the group is almost entirely horizontal. There’s hardly any vertical dispersion whatsoever. At this point I would be suspecting something mechanical. But we had already ruled out the scope & moderator, and the design of the Blaser stock is so simple that there’s really nothing to go wrong.
Have you ever heard of a barrel behaving this way?
Is this what happens when a barrel gets shot out?
