That article (on WWW.LARRYWILLIS.COM
) actually covers two separate topics. (1) Accurately minimizing chamber clearance using a comparator
, and (2) it explains the most common handloading problem with belted magnum calibers.
I often use this page to explain both topics together, because it helps shooters see how their handloads bulge and why head separations occur.
When shooters start to grind (or polish) their dies, there is usually another cause for their problem. It's usually related to their die height adjustment.
Three of my patented tools are now used by well over 6,000 shooters. I've found that some shooters are happy using familiar equipment that they have always used, and that's perfectly OK. However, there are a whole lot of shooters that want to do a little better.
