If you own one as described, you can certainly shoot some sporting and have a lot of fun. Is it ideal ? No not really but if open choked, ideal for the close fast ones and rabbits!
Truthfully, while I do own a 32" Guerini Sporter and find it great for Sporting, I can do quite well using my 26" SKT/SKT barreled field configured Browning Superposed if the targets are not too far beyond 35 yd's and is death personified on the rabbits!
If you are looking to purchase a field O/U specifically to shoot sporting, a better choice would likely be a 30" barreled one with choke tubes or fixed chokes adjusted to IC/IC or LM/LM.
