I forgot which forum I read this from, but one user bought a box and compared them with a retail box of Golden Sabres. By all accounts, they are identical cartridges and loadings with one very notable exception. The QA on the RUHD bullets were very inconsistent. The hollow point cavity for example, varied in depth and edge width. The obvious conclusion was that the RUHD line is simply a means for Remington to sell the non-perfect (but still functional) bullets that could not be used for the higher end GS line, which has to follow a more strict QA protocol to remain competitive for LE contracts.
You may be able to find the post I am referring too using Google.
