[QUOTE="swampratt, post: 2780437, member: 15054"] The Rugers can take a hotter load than some other guns and maybe the old manuals were catering to the stout Rugers. No kidding things change all the time. And if you really try to narrow down what will change velocity from your load to the book load there would be a long list of things. Lets see if I can name them all. If i leave something out then post what you think will change. Assuming the only things that are the same is bullet weight and the Type of gun used. 1: the brass brand you choose 2: the ID and OD of the brass before loading. 3: Springback of brass. 4: Volume of brass. 5: Primer hole size. 6: The amount of crimp. 7: surface texture of case ID. (will that make a difference) 8: primer used. 9: powder lot numbers. 10: Bullet lube. 11: bullet alloy. 12: OAL of loader round. 13: Chamber size in gun. 14: Barrel inside diameter. 15: Barrel finish on the inside.(slick or rough) 16: Bullet lot numbers Sometimes there is a major change in the shape of the bullet. (Yes I found this out) feel free to add to this mess. [/QUOTE]
