I have been using the Past recoil pad for the past two years and have done fairly OK (not well, not bad...OK) with it. There is a loss of touch with the shoulder mounted recoil pad that I have found necessary to shoot at peak performance at least with my gun. I have a definite flinch when shooting my 30br and I am considering a thick kick-eeze recoil pad that I saw down in Maryland. I found that "driving" with the shoulder (light touch that allows the shoulder to "catch" the gun) yields best results, but I haven't been able to get past the flinch to abandon the pad. I tried pinning my rifle and had some good results with it at 200yds. I don't know why, but at 100yds I couldn't get it to give me consistent POI so I went back to free recoil with the shoulder pad in place. Need more practice!! This is all score shooting if that makes a difference.
After using the past pad for the past two seasons i can say that it takes a level of practice to get your technique down to compensate for the space needed to shoot free recoil. I have a very specific bench position and procedure during recoil that I must follow or else I will bump the rifle. If the condition changes and I must wait, I always make sure that I haven't crept up on the rifle and always make sure I am as square to the gun as possible.
Hope this helps.
