I’m new to the forum and although getting old, new to older single shot rifles. 

My wife has chosen a No.2 RB as the platform to build her 22BPCR rifle. Our rifle has a decent trigger but a good deal of travel. It appears to me that it would be feasible to drill and tap a hole from  the upper radius behind the trigger guard to a location behind the trigger near the location the sear enters the rear of the trigger. With a set screw and Allen wrench you could then easily adjust the sear engagement on the hammer. Simultaneously adjusting sear engagement, removing trigger slack and travel. likely remove a little pull weight by essentially preloading the trigger as well.  Not an Anschutz trigger but an improvement.

Now, I have thick skin and no experience with the RB. This may be a dumb idea based on my ignorance of the action. Any thoughts or experiences would be appreciated.  I may be learning as I age. Younger me would do then ask. 

Thanks
