I have recently started using a wilson case lenth gauge for my .308 loads....
I've know wilson gauges have been around for years...It's just recently that I started using one...
Have to say they are great...especially for making up cartridges that go into semi autos.
I guess I'll still neck size for the bolt action guns...but this was one of those really neat reloading tools I wish I'd bought and started using sooner...
