I've been bitten by the rook bug and just aqquired my first rook rifle, a 300 H&H rook rifle. I have done a little searching but
have found very little info on this cartridge. I have found some
new brass now need to find a source for bullets and reloading info and ballistic information, Seems to have been a popular cartridge in its day and look forward to opinions on the cartridge and info on reloading it.
