O.K. guys ,I give. Starrett mic's are not to be trusted. Bullet dia. doesn't really matter. And put your faith in trial&error. I have to wonder if you approach your powder charges the same way?
Don't trust your powder scales.Powder charge weight doesn't really matter . All that matters is how your gun shoots that load. I stand by my original post. I ordered .451 dia bullets from X-Treme Bullets and received bullets .452 in dia. I have contacted X-Treme Bullets about this matter, but they have yet to respond. I was merely trying to determine if anyone had a similar experience with this manufacture? I didn't mean to ruffle any feathers.
