Why do you want a 2 grand gun to shoot in your garden??
When you say pellet fussy barrels or fussy barrels that would be the Styer( the new one )
What are you shooting at ? at what distance ?
If you want to knock over a 40mm target at 55yds then a Walther,AA pro Target or any of the AA variants or older Styers will do the job.
If you want to put pellet on at 55yds then I would go for the Anschutz 9003 ( once its been sorted )
I think for back garden your HW is as good as any.
