Almost the only twin-hunt Doubles method that is commonly rung is Grandsire. The 2 also rings plain hunt in the plain course, but is affected by the calls. As you can see, the plain course is relatively simple - the three working bells each do 3rds, 4-5 down, 4-5 up. Note the starts - the 4th and 5th each begin by making a point to finish off their dodges. The hunt bell (shown in green) keeps hunting until a Bob or a Single is called. See here for information about Bobs and Singles.
The next method is Antelope, which has 4-5 places instead of dodges. Note that the effect of making 5ths and lying behind is that you do 3 blows in 5ths place altogether.
All these methods are related to the single-hunt Minimus methods. Although there are eleven plain Minimus methods, three of them have 6 blows in one place, so the doubles versions are not allowed, leaving just eight.
The other six methods are:
Breaston Bob
Spondon Bob
Reverse Grandsire
Reverse Antelope
Double Grandsire
Double Antelope
You can also ring these methods with the 3 as the hunt bell, but the Central
Council doesn't recognise these as distinct methods, just as same ones starting
in a different place:
New Grandsire
New Antelope
Reverse New Grandsire
Reverse New Antelope
Another interesting group of methods has the 5 plain hunting as the other hunt
bell:
Bedfont Place
Double Portington Place
Cranbourne Place
