get a bore attachment to a screw gun or drill.
In Full bore ball valve, The bore dia will be same as internal dia of the pipe.In reduced bore, the bore dia is reduced than the ID of pipe.
to counter sink the screw means the screw head should lay under the wood surface-- the head should not stick up past the surface of the wood to do this I use my drill with a Phillips head bit and bore a hole in the wood while swirling my wrist and pushing down to widen the hole a bit-- this makes the head hole a bit larger and allows the screw head to sink below the wood surface without creating any wood splintering around the top of the hole by over forcing the screw

Below 2" is small bore
Try getting the point of a utility knife blade under the edge of the screw and pry upward as you attempt to back the screw out with a screwdriver. Once the screw is out far enough, you can grasp it with pliers and unscrew it the rest of the way. If all else fails, bore through the screw with a drill bit.

A black powder rifle with a bullet in the bore should be treated with great care as a loaded firearm, as if there is a bullet in the bore, there is probably also powder. Thomson Center make a little device that uses CO2 cartridges to safely unload black powder firearms - basically you insert the tapered needle on the device into the nipple or touch hole of the gun, and then squeeze the actuator of the device which releases compressed gas to push the load from the muzzle. Unfortunately these devices cost around $60 or so, Otherwise the standard approach to removing a ball would be to use a wooden or brass cleaning rod designed to take screw attachments along with a bullet-removing screw. This is essentially just a coarse threaded screw that you screw into the lead ball by turning the rod as you push gently. Pure lead balls, as generally used in muzzleloaders, should be quite easy to screw into. Once the screw is firmly seated, you pull on the rod to extract the ball. This should work fine for a standard patched ball or similar. If someone has jammed an over-size ball down the bore it may be more of a problem, as if the ball is excessively tight in the bore, the screw may simply tear out of the soft lead. These are the two basic methods - gas ejector or extractor screw on a rod.
The rear caliper compresses into the bore by rotating the face clockwise. You can do this with a special tool or with long, needle nose pliers. Unlike the front calipers, the piston extends and retracts on a spiral screw attached to the bottom of the caliper bore.

A screw is self fastening, as it bores out and threads the hole it goes into. A bolt does not bore out its own hole, and requires an additional fastener (a nut) if if goes into a hole which is not threaded.
Take it to a gunsmith. There is a tool called an E-Z-out- looks like a coarse thread drill bit, with LEFT handed threads. The smith will use a milling machine to bore into the center of the screw, and use the E-Z-Out to remove the screw.
