My reasonings behind buying a R8 are numerous. Some, people will disagree with but that's OK. Your money, your choices. Here are some of mine.
1. Most of my hunts are fly in or we go in on ATV's. Take down rifles are much easier to travel with.
2. Blasers do not require any tinkering or messing around. No trigger jobs, no glass bedding, no messing around trying to find out if you need to add forearm pressure, etc. They just shoot good.
3. I often hunt in cold, wet, and freezing weather. Based on my own personal experiences these conditions can cause a rifle with an enclosed style trigger, such as a Remington or Tikka, to freeze up because once water gets inside the trigger it is hard to get it out. This is a primary reason why many old Alaskan hunters stick with the old style Winchester 70's or Ruger 77's because of the open style triggers. The R8 allows me to take the trigger inside the tent at night to completely dry it out every night if needed. Generally it is not good advice to bring in a entire rifle into a warm tent every night and then expose it to freezing conditions again due to condensation and potential freezing issues.
4. As a lefty Blaser offers many more calibers than any other manufacture. Period. Pricey, yes. However different barrels take up less room in the safe than complete rifles. And 99% of thieves wouldn't know what a Blaser barrel was anyhow so the chance of them being stolen are less.
5. You never hear of hunters having feeding issues with a Blaser. The straight pull bolt and magazine system just works well. And once you are used to it, a conventional bolt action can't come close to the speed you can work the Blaser bolt.
Cheers.
