Do any of you guys shoot this cal. pistol barrel on your ENCORE ? Thinking about buying one , but was looking for basiclly a review to see if this is a worthwhile endevour or a waste of time ? I dont know much about this caliber and am hoping its going to be quieter than a 22lr ? How is sub-sonic ammo on this set-up , or do they make sub-sonic for the 17hmr? If you guys have one to sell let me know.I am going after groundhogs on ditch banks , I hope.
