[QUOTE="MontanaRifleman, post: 756844, member: 11717"] I think you missed a little of the exchange. The throat area is [U]not[/U] the same diameter as the bullet. Most throat's are .0005 to .001 greater in diameter than cal. I.e., a .308 throat may be .3085 or .309 in diameter. Not to mention that most bullets are actually .0005 to .001 less than cal, so there is going to be space between the bullet bearing surface and the throat wall. How much that affects accuracy vs your throat length is debatable and every chamber, load, bullet combination will have a unique personality. I personally would not throat a RUM more than .300 and would prefer about .200 [/QUOTE]
