It seems that there is a forumla at work here.

<br>Bigbore equals what ever the largest caliber firearm I own and up. Hence, if you own a .338/xxx big bore is .338 and up.
<br>
<br>If the largest firearme is a .40 the .40+ is a big bore and so on. If the largest firearm owned is a .270 then .270 and up are big bore
<br>
<br>Most of what I read has .458 and up is big bore., .338-.40 is medium, Below .338 is small bore.---but what do I know I thougth a .458 Win was big bore until I shot a .50BMG!!!
