Hello all, it's the new guy again. My previous reloading has all been with single stage presses. I have just purchased a Dillon 550. I will be loading .38-40, .44-40, and .45LC. As the first two are just necked down .45LC cases, and all three calibers can be safely loaded with the same moderate powder load (for CAS shooting purposes anyway), my question to experienced Dillon 550 loaders is; can I use the .45LC conversion kit with .38-40 & .44-40? Is there a function that takes place with the powder insert besides guiding the powder into the case? Any help would be appreciated. Thanks.
