Unless you have the equipment this may be one of those things that the cost of the tools is equal to or more expensive than paying a Gunsmith to do it for you.
After making triple-sure gun is unloaded (you could remove trigger group as a precaution), you could put a thread down the top of your barrel and receiver with the ends taped with masking tape. Now you can lightly clamp the gun in a padded vise and look at it carefully from both ends. The human eye is good at centering things, especially if you can step back a bit.
Mark your bead location and check again to see if it looks centered from both ends, from above, etc. I got drill bit and tap as a set from Midway, IIRC. I bought the replacement bead at the same time. I don't suggest re-using the bead. You don't know what its threading is, and it's hard to discern with such a small object.
Make sure to clean up the hole after drilling and after tapping, being very careful not to mess up the threads. Check to make sure your bead's shank doesn't protrude into the barrel. I'd use a file to shorten it, if needed, and I use a tiny drop of blue Loctite on shotgun bead threads.
All my best,
Wrap a doubled strand of fine wire or monofilament line around the bead and stretch it back over the center of the groove in the top of the receiver.
Then mark the new location with a center punch between the wires.
It will be as perfectly centered as the factory bead was centered.
I was thinking & typing while Bob was posting!
Hopes this helps.
