No thanks. No need.
Factory 440 hardcast out of the big Smith run over 1600 and they can be handloaded several hundred fps faster, but the Smith is a much heavier revolver, ported, and with a different grip frame and grip than a FA. Apples and oranges.
I mostly loaded 275 Barnes and 300 grain Gold Dots for my 500. Very accurate, not bad recoil-wise (I loaded them max), and very effective, which I never wondered about.
I loaded some 700 grain hardcast (just had to try them
) for the Smith and chrono'ed the top loads at 1300. Ended up selling most of them as I had no desire to shoot the rest and no idea what I needed them for, unless Jurassic Park became a reality.
I've never been fond of magnum SSA style revolvers ever since I shot a friends 44 mag Super Blackhawk back in the 70's. I've never liked the roll in the shooting hand. I prefer a Redhawk, Smith, or Taurus double action style revolver with heavy kickers. I've heard the Bisley grip lends much to recoil control and tolerance and was on the lookout for a 45 convertible, until this RB came up. So far I'm very pleased with it.
