RE: 30.06 = shoulder turned to hamburger
40 shots with a 30.06 is a lot in one session. I' m pretty sure your shoulder will be very sore on Thursday, which might make your getting 1MOA tough to do, if not impossible. Here is my very cheap cure, and one that I still do often as for some reason I HATE recoil. Find a big old fat padded leather glove or mitten, stick it in your shirt or even tape it (duct tape) to your rifle stock. I sounds stupid but it will work wonders and probably you have one lying around the house. No need to buy a new recoil pad, at least not right away. Once you are out hunting you won' t notice the recoil, but you will know that you are able to hit your target without flinching.
