I don't have an R3 but I do have the new limbsaver pad that the R3 originated from. I have never used a pad that performed that well. The recoil of my 30-06 with 180gr rounds has less felt recoil than a 270 or 308 with lighter bullets. I developed a flinch after shooting slugs through my 12 ga. I couldn't break this until I got one of these pads. Now I can shoot all morning long with no unpleasantness at all, no flinching, and shooting became fun again. If I got another rifle, I wouldn't even consider another pad after using this one. You can get them either prefit for many models or a grind to fit model, both for $30 from Cabelas. The only draw back to an R3 or a regular limbsaver pad is that they are only for synthetic stocks.The grind to fit model might work on wood stocks, but I don't know.
