I had one of the Browning model 71's, (Basically the same gun as the 1886 except for caliber and butt stock shape).
They are beautifully made rifles. Slick action, reliable, and accurate. Their action puts a Winchester model 94 to shame in smoothness and strength.
The price seems a little salty for a grade 1, but they seem to go up every year, so maybe not. Don't let the Japanese manufacture throw you, my Browning 71 was just as well made, if not better than my original Winchester 71 made in the 1950's. The Brownings were made in limited numbers, a very close copy of the original. Later Winchester marked Jap models used a different rebounding hammer, and a safety, if I remember right. I do remember the later Win. models did not seem as nice as the earlier Brownings.
The 45-70 and close to medium range elk go together like peanut butter and jelly. You might find that curved "rifle" butt a little harder on the shoulder than a flat, "shotgun" style used on modern rifles.
