If you ever want to convert it to a 460R let me know.
We have been taking the Smith 45ACP revolvers and reaming them out to 460R and they are F-U-N fun, still able to use 45ACP and 45AR due to the moon clip, but my point is that the 460R offers a significant increase in power over the .45ACP and .45 Super. Higher pressure and more powder capacity.
You may also play around with seating your bullets out a little since you can use the extra lead for slightly higher powder capacity, just watch it as you'll also be decreasing the bullet jump and it may spike on you.
