How to tell the Difference between a 303 and a 308 British enfield rifle?

Ive been told by two people one said it is a 308 and other said it is a 303 how do i know the difference so i know what ammo to buy i cant find any markings that will tell me weather it shots 303 or 308

ok 2 types of fiber Soluable and insoluable,soluable fiber is absorbed thru the body and have been proven to reduce colestrol and blood sugar levels,examles of soluable fiber are dried peas beans apples carrots potatoes barley and oatsInsoluable fiber is NOT absorbed thru the body but they assist in digestion and regularity examples are wheat bran whole grains legumes cabbage beets cauliflauer brussels sprouts .recomended 25-30 grams a day 5-7 soluable and 15-23 insoluableand remember suppliments do not provide nutrient related health benefits that consuming fiber does

Fiber is the nondigestable parts of fruit and vegetables that make you feel full and cleanse your intestinesST
