Question on Trapdoor sights.
« on: September 26, 2013, 11:30:58 PM »
Had my Trapdoor out today which as the M1879 sights on it.

Loaded with the Lyman 405 and 65gr of 2f, the rifle shoots so well I'm going to sell my Sharps, but it shoots about 3" right at a hundred yards. With the Buffington I guess this would be no problem but as the sights I have do not allow any windage adjustment, I'm wondering if any of you soldier boys who shoot the same gun know any magic I could try to get poa and poi to be the same?

There is a version of the 1879 that is windage adjustable. Past that I don't know of any tricks that will help.

If you have the Model 1879 rear sight - and the buckhorn has a screw on either side - it's adjustable for windage.

Just un-screw each of them, and move the buckhorn to whatever side, and tighten.

Thanks for the replies.

Yep, this sight setup is adjustable for windage, but unfortunately not at the 100yd zero position because the centering pin is in the way.

I had wanted to get around that problem so I could use the sights as regulated, but looks like I'll have to install a higher front so I can slide the rear higher where the windage becomes adjustable. Guess sometimes you just can't have it all. Oh well.

I guess the Army at the time figured a 500 grain bullet that hit 3" off center on your opponent was still going to do the job!

At 100 yards - that was getting pretty close to bayonet range...
