I think that once you start to break 25s and 50s on a regular basis, it is time to think how competative you want to be at your sport. You might then want to look for a gun that is built to last for life and is tweaked especially for you. Once you are at the peak of your game you will have less worry about changing or rebuilding equipment........or you can do what Arnold Reiger did and that was to kick ass with his model 37 winchester til it wore out then go to a used model 12 that he liked, and continue to kick ass.
