I've been using BLO on all my military rifle stocks for years. I love the stuff, I dilute it a bit with mineral spirits on wooden stocks to help it absorb easier. I prefer a finish I can reapply when needed instead. I don't like "sealed" finishes because they require stripping for repair or else it looks like a cheap fix.
Be careful with Linseed oil rags... the rags can spontaneously combust...YIKES! I always keep rags I just used in a metal sink or in the middle of the shop floor if I leave for the night without cleaning up the shop.
I think I will stick with the mineral spirits for the horn grip and leave the BLO for my M1, M14, Finnish M39, Cetme, and all my other wooden toys hehehe...
