Terrible, you're only allowed to load enough shells for the targets presented, which is no more than two at a time, unless you're shooting report doubles in Skeet, which isn't even allowed other than for fun...
You're length of pull will be too short with a sporter stock and you'll want a minimum of 28 inch barrels with the ability to change choke constriction.
Most guys shoot doubles barrels because you can run two different chokes at once, for close and far shots. Most of the time you'll have a close crosser, or an away from you style trap shot or a way out crosser going the other direction. Having the ability to to run say, an improved cylinder and a modified or improved modified for reaching out gives you so much more flexibility.
If money is an issue, there are plenty of used 1100's, sx3's, and Beretta 391's for auto loaders and decent SKB, lanbers and citoris for less than a grand.
THE MOST IMPORTANT CONCERN IS THAT THE GUN FIT YOU! You could spend $10,000 on a Kriegoff or Blaser, but if it doesn't fit, you'll never break clays.
