Puff-Lon is a lubricating ballistic filler that eliminates the air space inside an ammunition cartridge and smoothes the barrel with its dry lubricants.
Testing of the product has shown an increase in accuracy of flat-base bullets with smokeless or black powder, decrease in total maintenance of a firearm and more reliable cycling of gas-operated automatics, especially with reduced loads.
Puff-Lon makes duplex loads possible and practical, isolates grease wads and can replace wads and gas checks. Works with manual or automated powder dispensers. Price: from $26. Contact Puff-Lon, (800) 369-4518, www.pufflon.com.
