P17 hits high(no worries) and left (big worry)

From the inside a ring or bulge looks like a shadow. You need a good clean oiled bore to see it well. You have to look from a bit of a distance back...12 inch...and look through the whole thing.

I just have a bit of a hard time believing anyone would shoot using the sight protective ears for a foresight...I have read about cases of it though. It's just that the ears are SO different from the front sight blade...you'll get it shooting though. Maybe it was just the wood bearing...

Well try believing me, because I've done it (with the Boer Mauser carbine, not an M1917). It is not a fairy tale.

So it looks a thousand or two off, canting the sight over left by a degree. Wouldn't my corrections be to the right then?

The original problem was that shifting the blade by 3/16" failed to shift the POI noticeably at 50 yards. The observed discrepancy of the witness marks cannot explain that observation. (The mismatch of the witness marks may be because the original barrel was removed and replaced.)
And the amount of tilt (if any) is no more than the variation that might be produced by a shooter.

Come on guys! Let's get real! Try drawing a vertical line 1/2" long (and even that is taller than a foresight blade) on a smooth vertical surface, without using a spirit level, and then check it afterwards with a level - which will be difficult for such a short line. If you get it right within 1 degree, you can congratulate yourself.

And none of this explains the failure to shift the POI by shifting the foresight blade.

Fair enough. I just though an M 1917 has a bold enough sight protector...well...
