Good luck for your friend. In getting it loaded, getting the brass and the safari.

It is possible a gunmaker may have re-regulated the barrels the same time as drilling the holes in it. Hope for your friend that was the case. Or it has been sold and possibly re-sold because it no longer regulates.

Like these Pedersoli .45/70's that have been re-chambered and how often they are re-sold again and again and again. Any reason?

Hopefully that .577 was cheap. Hope it works out for your friemd.
