That was not a reverse taper. It is from breach to muzzle.
Today I made a bump die to alter boolits from an RCBS mold to fit the rifle. When done the boolits measure .281" on the bore ride nose section and .293" on the drive bands. I used a flat nose punch to test the die and it looks about spot on for fit at the muzzle.
Now I have to make a better nose punch and will give them a try. I think this might get some decent accuracy out of it. I have still lost interest in keeping it but before I let it go I just want to get it to shoot. Kind of a never say die thing dont ya know.
