What caliber rifle are ya tryin to "de-recoil pad"? Annn have ya shot it yet? ] . I have the same sort and the recoil isn't bad with'm. (7Rm although the 300RUM is a little more "exciting".) . If you have already shot'm an dont like it I apologize just sharing my observation.
I have a 700 5R, and just replaced the pad on the HS stock with a grind-to-fit Pachmayr Decelerator. I:
1) I used a heat gun to loosen up the epoxy 2) Pried the old pad off with a Xacto knif 3) Sanded the stock down with a belt sander (since the new pad is significantly thicker, I wanted to keep the LOP about the same) 4) Drilled two holes in the dense foam inside, and epoxied wooden dowels in; I drilled holes in the dowels for screws 5) I filled the big void with BBs mixed with epoxy (based on someone elses recommendation here). I think I got about 2500 of them in there. This added a noticable amount of weight.. 6) I put epoxy on the pad, and then screwed it to the stock. Let it dry for 24 hours. 7) Sanded the pad down to match the stock. (mostly. I need to sand a bit more). But it's definitely better than the stock pad.
