Well I guess sometimes the stars do line up. I was having a problem with .515 cast not chambering after being sized to .510. Well a kind member told me that there are a number of rollers that may not have had the chambers reamed from the original 42MM to the 44MM even though the breach block had been changed to center-fire. He suggested I take one case and trim it to 42MM and seat a cast bullet and see if it will chamber, I did, and it did. In both the Remington and the Husquvarna. So that was a very nice surprise which now gives me two moulds that can be used that I thought I was going to have to sell since the cast bullets would not fit in my chambers.
