Can anyone tell me in broad strokes what the process is for converting an M1 or M2 .22 caliber Springfield to 22 Hornet? I am not looking for as step by step techinical conversion guide, but rathere more of a list of things to be done and considered. Obviously G&H and others did a few of these decades ago. I assume that these conversions were successful and that they worked. However, I have never examined one of them so I do not know if they then had to be a single shot or if the magazine was altered or replaced to allow proper feeding. Beyond altering the bolt face, what are the things that need to be done to the basic barreled action?

Thanks in advance for sharing what you know about this.
