Is amazing how a slight change in form could make a good slug .. go to a unusable slug.. I managed to get 9 boxes of the old. 30 47.5 g months ago they shot awesome from My uragan..purchased a sample of the same slug a week ago.. n the 3 weights 43g - 47g - 53g n I could see them spiral all the way..or going up n down as they like..switch to the old 47.5 everything went great again.. how are the .30 Nielsen working on your AGT guns..? Difference to the eye is hard to see..
