Hey Dusty,
I was able to track down a version of "Squirrel Hunters" that Jim Miller tabbed out in tabledit. It's DAD capo'd to A. The B part sounds right on, if it helps you. I'm unsure whether it is permissible to share it here, so I will just tell you it is on dulcimertabs.com. Thanks again for sharing your version and knowledge. I've about got it down!
Thank you Dusty!
Scott, I've attached here what I have so far. The A part is pretty good but I don't really have feel for the B part just yet. Because the tune is in A mixolydian you can't really play it in a drone style tuned DAd or DAA since the drones should be A and E rather than a D. In this arrangement, the chordal accompaniment is always found below the melody, so if you just want to play single notes, always play the highest note.
And if you have suggestions for revisions, let me know. I'm going to keep working on it and if I decide major changes are necessary, I'll re-post here.
I was wrong. The tab I have from Steve's book is "Squirrel Heads and Gravy". I can't believe I never noticed that "Squirrel Hunters" and "Hail Against the Barn Door" are the same tune, as I have loved the tune for years. Gettin' old I guess....Lol! Dusty, I would love to have a copy if you don't mind. Thank you so much!
Thank you Dusty. I actually think I have tab for "Squirrel Hunter" in one of Steve Seifert's books, but I will have to check after work. I'll certainly let you know.
Scott, the same thing happens to me all the time. I hear a piece of a tune and want to learn it but then at some point realize it's way more complicated than I thought. Once I spend hours tabbing out a long Irish tune, going note by note, and then with about two measure left I realized the melody went way down below the bass string, so it wasn't even possible to play on the dulcimer. I was so frustrated!
I have tabbed out in a chording style playing across all the strings one of the versions of The Squirrel Hunter that I found in SMN. It is pretty similar to Hail Against the Barn Door. If you're interested, let me know. I'd be happy to share it so long as you understand that it's a work in progress. When I tab out a tune I don't know that well I have to play it a bunch before I get the right feel, and then I adjust the tab based on how it felt under my fingers. I don't quite have the feel for the B part of this tune yet, so the tab will surely evolve.
Scott, many are the times when I have been enchanted by some tune only to realize later that it was way more complex than I thought. It's then simply a choice whether I tackle it or choose something a little more straightforward. 
I've found several SMN versions of Squirrel Hunter or The Squirrel Hunters. They all differ in the chording and the key signature, but the actual notes are pretty stable. The fact that the chords and the key signature differ is just a function of the fact that the tune's modal and it doesn't fit the conventions of western music notation very well. In the five or six versions I've looked at so far, the first two measures center on E and B notes and then the third measure goes to G before the turnaround in measure 4. The structure is similar to Red-Haired Boy or Salt Creek.
One challenge on the dulcimer is that the melody requires a G note in two different octaves. I'm pretty sure I can get the melody going across all the strings in a DAd tuning an using chords to avoid that low D string. In a drone style the tune is more challenging, at least to play it in A. I suppose you could tune EAD. The E and A would be reverse drones for the key of A and the melody could be played on the melody string starting on the 8th fret, going down to the 3 and up as high as 11 or 12.
That's a weird tuning, though, isn't it?
Be aware that there are variations in the tune(s), and also in the key i assume. You may find versions written out in other keys.
That's very helpful, Strumelia. The sheet music for Squirrel Hunter seems to be written in A mixolydian. It kind fools you, because there are two sharps, so we dulcimer players jump up and celebrate that it's in D or Bm. But the tune ends on an A. I'm gonna mess around with it a spell.
Some people also call that tune "The Squirrel Hunters" or "Squirrel Hunter". The tunes might be identical or just very similar, depending on whose version you are listening to. There is a lot of sheet music online for the squirrel version of "Hail...". There might only be small differences to work out between Squirrel.. and Hail.., if you need a start for a dulcimer version..
The only thing I found is some banjo tab . I can't even find sheet music for the tune. If I get some time in the next week or so I may try to figure it out by ear. I'll probably start on the guitar before I figure out what dulcimer tuning would work best.
Anyone happen to have tab for this song?
