What you describe I think is normal, the tangs pull down in to the slot as you tighten it up and with no barrel bands to hold it in place it would cause the muzzle to rise. Every Musket I have seen the tang exerts an upwards force on the barrel. Which I always assumed was by design so the barrel was not floating.
I always put on my Barrel Bands before tightening so to make sure I do everything the same way and I was taught that I should note how the screw on the tang lined up and always put it in the same place.
I had a similar problem one day and my shots were all over the place, it turned out I had not tightened the tang screw.
One an a 1/4 turn later everything else was fine.
Next time it happened I knew what to double check and sure enough...

Well, when putting the barrel back together after cleaning, I normally would tighten the tang screw up AFTER the barrel bands were put on. Last night, I tightened up the tang and noticed the muzzle rise up.
This is a Kit I build (traditions kit) and I think the barrel fit at the breach is not correct.
Just see what was going on, I stuck a piece of brass sheet past the tang to keep the barrel from rising up when tightening up the tang. 2 pics before the shim and 1 after.
How do I mark the high spot in the breech area to sand down? any tricks?
Also, are there any prefered methods to getting the barrel fit into the stock decent?
