Good evening. Could anyone advise on what i could expect on the accuracey and power from one of the above. Its in .22 and not had a chance to shoot it following a serious accident. I have read in John Walters book that it could deliver up to 600 fps in .22. He dose not state which pellet or the weight of same. Is it 5.6 or 5.5 ! I think its a very elegent little design myself, any advice on pellets to use !. All information gratefully accepted.
