Did you think you wouldn't have to do any load development? Hammers are completely different that ELD's, so you got lucky the 260 gr shot well with your same ELD load. Load development is generally very easy and quick, but you still have to do it. You'll get more velocity with Hammers over any cup and core bullet.
Listen Dennis, if you want some advice on loading Hammers, just ask. There are a lot of us on this site that have been loading these bullets for years. Some are extremely knowledgeable, and you even have the owner of Hammer Bullets on this site always willing to help. Butterbean is a wealth of knowledge and just a great dude. GLTaylor is also very knowledgeable and he took the time to organize an entire spreadsheet of members load data for both Hammer Hunters and Absolute Hammers.
