Do you include Red oil in your indictment?
Certainly. And most definitely with a wood like beech that is notorious for uneven stain absorption. I find it much more controllable to use either a home-brewed alcohol based alkanet stain or Behlen's SolarLuxe prior to applying my final finish. But if your unconventional furniture and cabinet finishing techniques give you the look you want on a gunstock, go for it.
Oh, I'm not recommending Japanese Shou Sugi Ban to gussy up this beech stock either, although that technique made some nice tool handles when I finished them. Too much potential for a bad result for a first try on a rifle.
