[QUOTE="Fiftydriver, post: 683232, member: 10"] One thing to keep in mind, since you have a contact point to the barrel that far from the receiver, you can expect that as the barrel gets hot, point of impact WILL rise to some degree. Now for the most part, three shot groups will not be effected much but if you are trying to punch 5-10 shot strings, expect to see some rise in your point of impact. This is simply from the barrel heating up, expanding and pushing down harder on the barrel pressure pad which in turn will elevate the bore slightly, as such, point of impact rises. Generally if removing the pressure pad degrades accuracy, you can live with this slight issue for better all around consistancy. Best cure, pull the barrel, get the receiver properly accurized, install new match grade barrel and restock!!! Thats the best way to get a true 1/2 moa rifle. [/QUOTE]
