Many moons ago my LBS recommended drilling a small hole in my BB shell on the steel frame I had, and since I have generally stuck with steel I have continued with this advice. Having recently aquired a another steel frame I just wondered if this advice is still good, given the several changes in BB design. Since the LBS that gave me this advice is long gone, I thought I’d ask you lot; so is there still a good reason to get me drill out? Ta

No problem at all. It is simply a drainage hole , cause that`s the lowest point. I usually drill 2 3mm holes just about where the threads end. The only thing is they need to be plumb(take a vertical line through the frame when the bike is stood normally)

I have done it with all my bikes. Ti included.
