Fist of all it took a while for me to check this out as each time it was used it had jammed around the last 6th or 7th last round so I had to check with a few gun experts to find out why, then to find that it was the flat tip on the bullets that had caused it. Those rounds where "CCi Blazer Brass Case Centerfire Cartridges & 147 grain", which hit the center of the targets much better than they usually do even with the targets twice as far back than usual.\r \r Pros:\r 1) Weight with it helps with recoil.\r 2) Rack and barrel didn't get too hot from firing 50 rounds.\r 3) Loading the 50 rounds was much smoother than one would think with that much spring load.\r \r Cons:\r 1) Instructions could be better on loading, as it took a while to figure that you have to lightly rotate drum to get shells to load even with using a Maglula UpLULA Speed Loader with a spacer/adapter.\r \r I was very pleased with how this works and will be ordering at least one more.
