I'M wondering if I took one of your 44s if I could bump it up to .451 on my Corbin press (s dies). Prolly too hard to.
There are a few people doing just that, even with reloading presses; but you need to anneal the cases first. Failing to anneal them results in the body not expanding uniformly. So, the base and body are not concentric. Obviously, that is not conducive to in-flight stability.
I believe BT_Sniper on castboolits even sells a "one step" die in .45 caliber, designed to use .40 S&W cases as jackets.
