when your buying a box of ammo what does the grin measure

example 30.06 150 grain - is this the weight of the bullet or the weight of the powder

which would be better for shooting farther 30-06 150 grain or 30-06 180 grain?

what im asking is does a bigger grain more powerfull and shoots faster and farther or a lighter grained bullet?

grain refers to the weight of the bullet. You rrifle will let you know which shoots better. Heavier grains are usually used for hunting but I find most plinking or target shooting rounds to be in the 150-165gr range.

in terms of distance- think about it in terms of gravity - the heavier bullet will start dropping quicker than the lighter one.

In terms of their purpose - generally I use a heavier bullet for knockdown power - 30.06 is a very versatile cartridge- evidenced by the wide range of loadings available for it, properly loaded it can be extremely effective on anything from prarie dogs up to deer and mule deer sized game. It all dependes on how the cartridge is loaded. I personally have shot everything in 30.06 from saboted 55 grain .223 bullets up to 190 grain boat tails.

The shape of the bullet also effects the flight. spire, Hollow point, round nose, flat, the more streamlined the pullet the better it flies.

Also, for reference, one grain is equal to 1/7,000th of a pound.
