... I was on a hunting trip out west and some of the dead pines had very interesting grain in them...
Some of the tightest curl and interesting grains and colors I've seen in green or
fresh killed wood (the colors fade quickly, and the woods weather away
fastly if left in the wilds) are squishy Soft maple, Boxelder, and Yellow Poplar. There can be blues and reds in the Boxelder and curl, Soft maple can develop the tightest curl I've ever seen (more than once) 'round here, and Poplar can have some purples and reds and blues and greens deep in the logs as you work them.
All beautiful woods*, but quite useless for hanging gun parts from-especially when the rest of the forest is Hard Maple, Cherry, Walnut, Ash, Oaks, Persimmon, Butternut, Sassafras, etc. This particular bit of the South is where Eastern Redcedar dominates and pine is mostly planted, and not naturally distributed, hence my unfamiliarity with most of them.
You might try Ash for a challenge, correct, and highly educational (as in teach the shop dog some new swear words).
*I do realize that many are "stabilizing" these pithy and soft woods (Boxelder especially) in order to make them into useful things (they stain them funky as well). That'd be fine for a modern or deep fantasy gun. But thankfully
we don't do that here-but also I'm sure there's a FB group for it!
