If your cases are the issue, it's your reloading practices that are the cause of the FTF, not the rifle.
As others have stated, brass doesn't just magically get shorter without the user doing the shortening.
Clean your die set, Start with fresh brass, make sure you size all of your brass at one time and see what happens ?
Take all of the measured shorter brass and toss them.
