hi mate, my 25 has been performing flawlessly and it always gives me alot of pleasure. the only one fault i have is the taper of the butt. when i shoot sometimes i notice that because of the quite pronounced taper the rifle moves slightly down at the butt and it causes me to hit slightly high, not enough to miss a rabbit but when im trying to squeeze 4 shots into a small group at extended ranges i have to be very careful. i might infact ask the stock maker to get an extension added to that part under the butt. it might not make it look that great but will shoot better off the bench.
there are about 3to4 good choices of pellets for the .25, in my experience H&N make the best one and has the most consistant lots. all those groups are shot with pellets out of the tin, no sorting except that i check if the skirt is uniform. if its not i throw it away because it will result in a lower POI.
the barrel cover is purely aesthetic and surves no particular purpose. hopefully i get to film some more this week as yesterday i had the video cam with a dead battery!
