I have some Barnes LRX 127gr and recently bought Berger VLD Hunting bullets. Berger says the best accuracy is touching the rifling but for hunting to back off at .020 for a good starting point. Also so you don't risk jamming into the rifling and pulling the bullet apart when ejecting. Redding makes a specific micrometer for the VLD and 26 Nosler. It's designed to be shaped for the sharper point of a VLD.Agreed, they are invaluable for load development. Especially when using bullets that are known to be picky about the seating depth. For example, the Barnes say to start .05 off the lands, but you will get varying results by adjusting that.
I was thinking of doing the same thing for now to save some money for the time being. I've just spent about 600 on a magneto speed v3 and other reloading stuff. So to fork out another $90 for a micrometer right now I'm hesitant. But if they are worth it I'll get one or 2 in the near future.I do very well with my non-micrometer Forster Benchrest Seater Die. All I need to do to is keep a "dummy" proof cartridge for every bullet I use. I just put the proof cartridge in my press to adjust my seater, and all my new cartridges will get exact match to seating depth of the proof cartridge. It's very easy to do.
