When one has but one gun, one shoots what one has. Wise selection of loads can help considerably with the handicaps of but one gun. Many/most shooters will buy purpose built guns as soon as they can afford to do so.

Brit "utility" (think BLNE) fowlers are generally proofed for 2 3/4" or 3" shells and, if one respects their service pressures, quite robust. They weigh, balance, and swing much like their American counterparts. Their price point was not all that different.
