If you disassembled a round of that stuff and had ONLY the original powder from that round to put back in to that round, a 5.0gr charge of that powder may very well not even get the bullet far in to the bore. It could move the bullet forward enough to lodge it in the barrel just enough where it will stop and allow the bit of gas to escape behind it out the cylinder gap.

However, if you had 5.0gr of a fast burning powder such as Titegroup or Bullseye then you would get a typical discharge/shot fired, but it wouldn’t have the power, bullet speed, deep sound or recoil that 14 grains of the slower burning (proper) powder would give it.

To actually do all of the above, you needn’t necessarily be skilled but you would need the proper tools, and only a handloader would have those tools available.
