    You have a Model 1917 not a P17.

    I did look for a bend. I did it by looking down the bore and looking down the length of the barrel like I did when I shot aluminum arrows and didn't see anything obvious. I didn't see a bulge but I admit that if it was small I could miss. would it stand out or is it a "trained eye" sort of thing? The bore does look real shiney and clean though. When I picked it up I cleaned the bore with lead and copper solvent and then cleaned until patches were clean. I would think a bulge would stand out right?

    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.

    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...

    I would also suggest that you try it will the standard 150 gr. bullet. Point of impact can be quite different from the 180 gr. The sights are regulated to be dead on at 300 yards if I remember right.

    I looked at the barrel again and can't see any shadows. So I am hoping it was the wood. Only problem is it will be 3 weeks before I can get back to the range.
    I will find some 150 grain and give that a try. I had 40 rds of 180 given to me 2 years ago and didn't own a 30.06.

    You simply must get back to us with the end result...we'd love to know.

    After all you guys have done, it would be the least I could do.
