forgive me for my ignorance, i only have just started reloading. can someone explain to me where the lands is?

Well, you got rifleing which consists of lands and grooves. Lands is the raised section and grooves are the lower sections. Depending on the type of rifling, where the rifling starts. Weatherbys start like 1/2" in front of the bullet. Most 06's and all start like .03" in front of the bullet.

Lands are found In the bore, ahead of the chamber and throat. (So are the grooves!)

When a barrel is made, a hole that the diameter the finished bore is to beis drilled and polished all the way through the barrel blank. For example, for a .308 Win., this hole is bored and finished at .300" of an inch in diameter.

Next,therifling grooves are each cut orembossed in the bore .004" deep, for a total groove diameter.308". When the grooves are finished, the "bore" part of the barrel wall, which was left in the original size of .300",now constitutethe "lands", and the deeper part is called the "grooves". Which, of course, they are..........

Take the bolt out of your rifle and look through the barrel from the breech end. See those spirals that go from the chamber forward to the muzzle end? Those are the "lands and grooves". They are together called "rifling", and are what makes a gun a "rifle"! They spin the bullet so it stays on course with the point forward...........
