Well I don't have any experience w/ the Pachmyer Decelerator.. I've had great luck w/ the Limbsavers pads. They do have prefit pads for most of the popular guns on the market. The new Remington R3 pad that comes on most of the newer Remingtons is just a private label limbsaver pad. You'll spend a little more $$$ for the prefit pads over the grind to fit... but it does look a little better.
