Ancient thread I know, but for others that may wind up here like myself... I have a near perfect solution. I was searching the internet for a replacement recoil pad for my remington 721 that was passed down to my oldest brother then to me. The original rubber recoil pad was hard as a rock making for one helluva kick from the 300 H&H Magnum rounds.
After alot of searching I came across "Kickeez Pre-fit Recoil Pads
". I measured my original rubber pad, printed a template from their site, and found a near perfect recoil pad match. Checkout their KZ-110 Recoil Pad
. A lil pricey at 47 bucks but looks like it will work.
Just adding my 2cents so that others that wind up here via a Google/Bing search may find a solution.
