At 50 yards that's pretty good accuracy for an iron sighted pistol.

What type or brand of ffg powder?
Maybe switching to fffg or P will help because it often burns cleaner and more consistent and is recommended for small calibers.
It's also possible that it's caused by the barrel warming up and the powder residue left in the barrel, so try swabbing out the barrel every few shots.
Try a lubed .015 patch for a tighter seal and more consistent velocity.
Then adjust the powder charge to obtain the best results.

If loading with 777 then ffg doesn't matter as much but try reducing the load in small increments.
Don't load 777 using very much compression.

If using powders other than 777 then use consistent compression when ramming the ball.
Sometimes using an over powder card or wad will help to promote more consistent velocity.
