[QUOTE="Gord0, post: 1470075, member: 99696"] As others have said, it will give you an area that you can repeatedly measure. The .3 cal bushing should be .3" diameter. Due to production tolerances that will vary slightly. That will tell you where on the bullet is .3" diameter. That won't tell you where your bullet will touch the lands which are at .3". The reason it won't is there is also a lead cut into the chamber, along with the bullets ogive profile. Find the lands using some of the methods described above, or with the Hornady length tool and then measure with the bushings. [/QUOTE]
