I like and have several Brococks in my kennel. However, recognizing that I may catch a load of crap about this, I would argue that the trigger is the biggest downside. It really is not a two stage trigger in the proper sense. The feel of the first stage is really just slack before the trigger touches the sear. That means you need to have the sear just on the breaking edge of firing to get a "good" trigger pull.
In a traditional two stage, the first stage advances the sear to the breaking edge, then the second stage is not significant. It also makes the gun safer by initially being far from the breaking edge.
Now, I do have several setup with 8 Oz pulls, but they are not hunting guns. They are great target guns and very pellet-friendly. However, I just have to be careful of a self-fire, due to the fact that the sear is on the breaking edge.
Due this, I have not had much success, yet, in getting a Sniper HP trigger down to an acceptable "Benchrest" level. Unfortunately, that pushed me to go with a FX Streamline. The Sniper HP was tuned very well for performance out of the box, though (.25 JSB King Heavy at 860 fps) .
Again, good rifles, but be aware of the trigger limitations.
