Ok, I’m getting ready to try 240gr plated bullets in my 629. Most of the searching I have done here said not to push plated bullets over 1200 fps. The lightest load I show in my Sierra book is 22gr of 4227. And that is listed at 1200 fps. The book warns not to go below minimum loads. The IMR website only lists 22gr of powder and says that is 1310 fps. And adds that is a compressed load. Obviously I need to research a new powder for this combo, but until I run out of 4227, can I back the load down to say 20.5gr? Or will I get into trouble? Thanks for any replies.
