If not then fire-forming is not necessary, just load and shoot normal loads and the brass will form itself off of the first firing..

The belt should be enough, but if it won't headspace, then it needs a false shoulder.

Replace the expander button with one slightly larger, expand the neck to the larger size then neck size partially to form a tight fitting partial shoulder. Then load and shoot...No Cream of Wheat or wasted bullets.

A 404 Jeffrey expander button is the next size up, but CH may have other options, they are close to being a custom die shop and the owner is friendly enough.

Thanks! I'm not sure how they improved the parent case. Bought the rifle on gunbroker without alot of information. The website from the die manufacturer is the only thing I found that had that caliber listed. A google search came up with zero information on the improved version. I may call the die shop once the rifle and dies arrive, and see what is different in the cases.
