[QUOTE="Varmint Hunter, post: 837021, member: 313"] While you are waiting for your equipment just use the reloading book info and go have some fun. BTW - the distance off the lands will be different for each different box of bullets due to the different nose profiles. Averaging all the bullets together tells you nothing. Once you have your measuring equipment you can make a chart for each different bullet. Generally, any given bullet of the same manufacturer, type & weight will remain fairly consistent from box to box. It is not a bad idea to re-check the distance to the lands once in awhile because throat erosion will cause the dimension to change. Lastly, don't be fooled into thinking that rifles only shoot best with bullets loaded close to the lands. Accuracy nodes can be found at almost any distance if you actually look for them. I own several rifles, factory and custom that shoot very well with bullets loaded wayyyyy off the lands. Typically, bullets that are loaded to a length that fits into the magazine of a factory rifle will be way off the lands. My hunting buddy prefers Weatherby Mark V rifles. Ammo that fits in the magazine is often .250" off the rifling. You would be amazed at how well he gets those rifles to shoot with a preferred handload. For a hunting rifle, I would start at magazine OAL and then seat bullets progressively deeper (within reason) until I found an OAL that produced smaller groups. [/QUOTE]
