I have been following the Long Range Muzzle Loader Match held every March at Oak Ridge, TN, for some time now. This is a tough match -- muzzleloaders with iron sights, 10 shots each at 200, 300, 600 and 1,000 yards.
Come to find out that David Minshall, a leader in long-range ML shooting in Great Britain, is ramrodding the 2024 match, which will be a re-creation of the Great Creedmoor Match of 1874, in which the Americans, shooting Sharps and Remington cartridge guns, beat the Irish team shooting Rigby muzzleloaders only because one of the Irishmen put one of his shots on the wrong target. My guess is this 150th-anniversary match will see a number of original Sharps and Rigby rifles on the line. Talk about stirring times, when riflemen were really "Riflemen"!

I’ve been thinking of this 150th anniversary match myself.
Would have to source sights for my Rigby but I wouldn’t hesitate to give it a try or even loan it out to a competitor if it shoots well enough (and I can’t...)
Also thinking I want to try the Quigley shoot this year with my Gibbs or Westley match rifles.
That would really be something.
Competing with original equipment.

Go for it friend!
Here's just one version of the Dr. Goodwin sight.

The Rigby has an integral mount on the tang otherwise it would be a simple task of fitting a base.
My plan is to buy a staff (or a complete sight) and file it to fit.
Actually need sights for the Gibbs too the front of which is a bit more complicated.

Huvius.

If you are interested in shooting Quigley, let me know, we have shot it 13 of the past 16 years. You know where to find me.

Dave

That would be great!
