A very interesting article,
I was very interested to see how popular the .25 calibre was. This calibre, along with .27 calibre have been the lost sheep of calibres mostly due to the slow twist of most rifles. Target rifles are custom built so you can have any twist you want but .25 seems to sit nicely between the two other favourites of 6 and 6.5 mm. I wonder what is next.
