I constantly see threads that speak of accurate groups of 1 - 3 inches at 10 yards. (people can throw rocks that accurately) if a gun won't hold at least a 5" group at 50 yds from a rest then it's not worth shooting. Get a ransom rest. Work with bullet type, seating depth and powder as they are different for each gun and each barrel. A great ammo in one gun it not always a great ammo in another gun.
