You would think that with a difference of .003 you are definately going to have some accuracy issues. I'm going to order a micrometer today, that way i can sort through my bullets and toss out the ones with most deviation.

The reason i asked about diameter of the bullet and then actually about the gas seal was because a friend wants to shoot all lead conicals. He didn't want to have to slug the barrel because it wouldn't do him any good without owning a micrometer to measure the slug, but he said that the powerbelts load really nice. Not too easy and not to hard, so he figured if we could ask someone the diameter of the Powerbelts/gas sealhe could order the lead conicals sized to that same diameter.

You know it would make sense for CVA to package the Powerbelts with a different size gas seal for those of us that have a larger bore.
