Lil? Gun is an advanced technology propellant designed for 410-bore shotshell reloaders. The 410 shotshell has long been difficult to load due to shortcomings in powder fit, metering, and burning characteristics, but no longer. Lil? Gun was designed to fit, meter and perform flawlessly in the 410-bore. No more spilled shot or bulged cases. In addition, Lil? Gun has many magnum pistol applications and is a superb choice for reloading the 22 Hornet.
