Their descriptions are pretty close to the same for both powders. Will be interesting to see how they do since I can't find Clays around here.
Hodgdon High Gun Smokeless Shotshell Powder
Description
High Gun is a flattened, spherical shotshell powder designed for light-target, handicap and super handicap loads in a 12-gauge shotgun.
This powder also closely duplicates Remington Nitro 27 factory loads.
High Gun’s geometry results in a powder that meters consistently, has excellent ignition and burns clean enough to throw uniform patterns clay after clay.
Hodgdon Perfect Pattern Smokeless Shotshell Powder
Description
Perfect Pattern is a fast-burning, flattened, spherical shotshell powder designed for light and extra-light field and target loads for the 12-gauge shotgun.
Its geometry and density results in excellent ignition, superb metering and low charge weights that deliver consistent patterns with mild report and low recoil.
