Hi dhg,
Here the barrel is fixed to receiver by thread and not interchangeable. Locking is in the receiver, steel on steel, only bolt head can be changed for ease of production and cost saving.
Used in some very cold parts of Europe (eastern and northern) with no problem.
The other rifles with alloy receiver, locking in barrel bushing and take down barrels seem to perform well also.
Most of time people using them don't play a lot with barrel.
The system is an option, a "plus" if you have special opportunies. Hunter who practice 80% driven hunt with a 9,3x62 and 20% stalking and mountain hunting can go to 270 or 7x64 to gain "ballistic LR advantage.
Or in Sweden where you are limited to 6 receivers (firearms)but where barrels are not counted.
You can have different forearm and heavy target 6,5x55 or 308 barrel...
The principle works, accuracy is as good as most of the well advertised LR rig.
You must know that, as a Blaser guy.
