Did those original rifles have progressive depth rifling?Bobby Hoyt's recommended twist for a mini is 1 in 60" and the original Zouaves, .58 Mississipies and '61 and later Springfields were even slower than that.

The Springfields did, I'm not sure about the Zouave and Mississippi.Did those original rifles have progressive depth rifling?
If you make new front sight make it at least 4x height of original then trim it to POI of range choice.I appreciate the good ideas I’ve been given here. Putting tape on the rear sight is worth trying and not permanent in any way. The front has definitely got to go. I mean if you could look down the top of the barrel from the tang you’d see what I mean. It’s probably about 1/8” off to the right. The gun predictably hits left, and the further the target the further left the gun hits. It’s about a foot high and left at 100 to the center of the “pumpkin”. I’m going to fire some groups with prb at 30 yards from a bench in a couple of days. I’ll report back and take some pics of the muzzle end while I’m at it.
Your memory is correct. The witness marks on mine line up. The rear sight is centered in line with the tang. It’s just the front that’s canted.If I remember right, the Zoli Zouave is only held into the stock with the tang screw and barrel bands. If BOTH sights are off in the same direction, it could possibly have been un-breached at some time and never tightened properly. Check the witness mark on the barrel bottom and the tang. They should line up. If not, the breech plug will need to be tightened and the witness marks aligned.
TN ghost is right! My brother had a Zouave that would not group well at all. He was fortunate to find as utter at the 18th century trade fair at Fort Frederick that had many different size for sale. He explained to my brother that the correct size should drop quite slowly down a clean barrel when held vertically. The Minnesota would be unlabeled for this test. The Minnesota should displace the air on its trip down and go down like an elevator as opposed to dropping fast. He ended up selecting on .002 larger and sail his groups went from poor to extremely accurate.I'll have to second the JB weld option. It is a great way to "form" new sights on the gun and experiment in a non permanent and easy to change fashion. It is often used by competition shooters.
As far as the Zoli Zuoave, I have one as well and read some info that they were sensitive to diameter on the Minies, many of them liking larger diameter projectiles. I went from Lee molds .575-500 M and 575-474M (target Minie) to a .578-478M and my groups got smaller.
You also have to consider in load development, getting a load stout enough to bump the skirt out to engage the rifling properly, but not overly so to "blow" it out or damage it as it leaves the barrel. Skirt thickness, powder charge and bullet alloy all play a role here.
I'll look and see if I can find the article I read that led me to the larger diameter projectiles to post it up. It was really good and in depth
Dang spell check! Should have been suttler in the above.TN ghost is right! My brother had a Zouave that would not group well at all.

I figured Minnesota meant minié tooDang spell check! Should have been suttler in the above.
How about some pics? Getting close to a thousand words...
