I have owned Lightening XLs in all three calibres, all shot well, but I did have problems finding a pellet that fitted ok in the .177, Accupell were the only ones that fitted straght from the tin. I had the same problem with the .25, pellets very tight fit in the end I got PCMB to make me pellet sizers which sorted out the problem. I only have the .25 now and would not get rid of it. Its very accurate out to 35yds and hard hitting.
