From my years of doing gunsmithing I found that WD-40 will gum up over time and will make normally free moving parts require solvents and force to free them up. This won't happen over a weekend or even a year, but eventually you'll have a big problem. I'll concede that just wiping down the barrel and receiver after a shooting session will likely do no harm, but refrain from using it on the internal mechanisms that don't get taken down and thoroughly cleaned often.

The Imperial German Army in WW1 and the Wehrmacht of War2 and even the early Bundeswehr couldn’t ALL be wrong on Ballistol. It was originally intended for everything- guns, wood, steel, cleaning just about everything, wounds, on and on and on. Old German soldiers told me it gummed up in Russia in the winter but everything gummed up in Russia in the winter. It has done a beautiful job of restoring a leather topped mahogany veneer antique card table for me. I use it on most anything that doesn’t get ugly cold.

I don’t intentionally use Balistiol on wood but don’t worry about it getting on wood stocks when wiping the gun down. In bores it’s very good. Tough clean job let it sit overnight then wipe. Stocks warmed soft wax light coat hand rubbed my choice. Spill over on metal no problem. Some guns wax the whole thing.

WD 40 is the best choice for very little . I do use it as a cutting fluid, taping drilling turning or milling aluminum. Not as good as Tap Magic but cheaper.

I use it on both wood and metal. For wood, the only caution is to use sparingly. I generally wipe the wood with a dry cloth before shooting. Ballistol does get a little slippery.
