RCBS vs. Hornady chamber tools
Posted: Sun Nov 20, 2011 1:31 pm
Just thought you guys would be interested in something I've discovered.
We all know that the Savage .204 throats are long. I have 2 tools that I've used to find the the distance to the lands.
Using the RCBS tool, I was getting pretty consistent results. But when I used the Hornady tool, I was getting dramatically different measurements. After some head scratching, I found a glaring problem. The RCBS tool spud doesn't reach the lands in spite of getting what feels like a good, solid seat.
Here's a pic of the difference when used in my chamber:
What is happening is that the shoulder portion of the RCBS tool is what is stopping forward movement. It's just measuring the distance to the shoulder datum.
