After the rifle is assembled at the factory, the fore-end wood dries for years, and shrinks, and is very tight against the front band screw.
Tap the screw out with a brass (not steel) drift pin. And yea, you have to hit it hard.
After you get it out, find a drill bit that fits the hole in the stock EXACTLY, and then go up to the next sized bit that is 1/64th of an inch larger. Use this up-sized bit to drill out the hole in the stock, to enlarge it. After this, you should not have alot of problems re-installing the stock and barrel band, and the stock and band will still be very tight.
If you still have problems reinstalling, then go up in size again to a larger drill bit (1/32nd of an inch larger than the original exact bit), and redrill again. This should do it.
