510 GNR

Research notes

The 510 GNR was developed by Gary Reeder from Rheeder Custom Guns, Flagstaff, AZ around 2004 and is based on the 500 Linebaugh case that was shortened by about 1/10th of an inch. It allows for the cartridge to be downloaded to about .500 Special ballistics and upward to 500 Linebaugh, which makes a very versatile cartridge for a variety of hunting/shooting conditions.
