I called a friend and found out he had a small set of hollow ground tips and a handle that I could borrow.  So far I've only used three of the sizes, but each worked very, very well.  I was pleasantly surprised to find that all the screws I removed were not at all difficult.  I don't think this thing has been used since it left a cleaning and repair session at Springfield sometime after 1900.  There was very little rust, but a fair amount of hardened grease and oil.  The screws were snug, but not so tight that just a bit of firm pressure could remove each one. 

If everything continues so well, I will be very pleased and after reading Butlersrangers post about bolt removal, I'm going to try that as well later today.

I am also considering using some Murphey's Wood Soap on the stock. It seems a little oily and very dark.  In some spots it is also greasy or sticky. but no damage or cracks. After I get it well dried, I think it will just need some Linseed oil and it will look a lot better.  Any thoughts?

I thank all you guys for your comments.  You've been a big help and convinced me I need to get a set of better, hollow ground screw drivers.
