Thread: Swapping reloads between rifles

I dont think thats quite correct. Factory ammo is made to fit easily into the minimum chamber dimension for calibre. Therefore theres lots of expansion going on even in a tight chamber. I see its a federal case, interestingly all the case related reloading problems Ive encountered have been with that brand.
