Tests conducted with the improved shot cartridge.  All tests conducted with 1 1/8 ounces of Number 4 shot at 30 yards.  The propellent was 3 1/4 drams of Goex FFg.  A total of 14 test patterns were shot. 

The barrels were not cleaned prior to conducting the tests. The cartridges were lubed with Crisco/paraffin/bees wax.  The base of each cartridge was filled with the lube.  The barrels became noticeably cleaner as testing progressed.  The lube saturated base wad impacted the patterning paper on several occasions.

The Right Barrel had a Carlson Modified Choke Tube and was shot first.

The Left Barrel had a Pederoli Modified Choke Tube and was shot second.
