REDDING BUSHING .339 TITANIUM COATED

surface treatment to further increase the effective surface hardness and reduce sizing friction. The proper bushing size can be easily determined by measuring the outside neck diameter of your loaded cartridges with a precision micrometer. Then, simply subtract .001" from the cartridge that had the smallest average neck diameter. Moly coated bullets may require tighter necks and the use of bushings .001” or .002” smaller.
