Is there a way to draw a solid horizontal line in a buffer?
Both hypens and underscores, at least in the font I use,
have gaps between them.

Monospaced fonts are usually designed in such way that various dashes
typeset next to each other form a continuous line.

You may try to insert an image with a line as Emacs support several type
of images.

Check out this function:

    (defun insert-image-file (file)
      "Insert an image from FILE in the current buffer at point"
      (interactive "fImage file name: ")
      (insert-image (create-image file)))

You may call it interactively via `M-x insert-image-file` or use it from
your Emacs Lisp code like `(insert-image-file "horizontal-line.png")`.

You could use characters from the Box Drawing block in Unicode (U 
+2500-U+257F), for example:

	────	BOX DRAWINGS LIGHT HORIZONTAL @ U+2500
	━━━━	BOX DRAWINGS HEAVY HORIZONTAL @ U+2501

A few fonts have these characters: FreeMono (FreeSans, FreeSerif),  
DejaVu Sans Mono, Monospace, Unicode Symbols ...

C-u 80 C-q 1110041
or evaluate   
(make-string 80 ?\u2501)

This gives
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

which should appear as a solid horizontal line if you have unicode support.
See http://www.unicode.org/charts/PDF/U2500.pdf for the list of unicodes
related to box drawing. Some examples:

(make-string 80 ?\u2500)
────────────────────────────────────────────────────────────────────────────────

(insert "\n\u256D\u2500\u256E\n\u2502\u2660\u2502\n\u2570\u2500\u256F\n")
