I have used both stocks and they are both superb. They are very different tho. The McHale is BIG, very nice large near vertical pistol grip, very large forend. It is heavy and designed for big barrrels. It fits my big hands perfectly. This is not a carrying stock, but it is a wonderful accuracy platform.
The A-5 is also a superb fitting stock, and it is somewhat lighter and less bulky. Also has a great near vertical pistol grip, more rounded and neater forend.
Neither of these stocks are as good for hunting as the A-1, it is the answer if you ask me. I would have preferred a little bigger pistol grip on it, but otherwise it is a great handling and feeling stock.
Good luck with your decision - those are my favorite stocks and I would choose depending on how heavy I want the rifle, plus if I am carrying it much.
