I have a Remington SPR-94 (Baikal) .22LR/.410 combo. It has interchangeable chokes and currently has a scope on it. I use it for pest control and having the versatility of both rounds available to me has come in handy, but is not a necessity. I like it as a tool. It is accurate enough, reliable enough, but really not spectacular in any way. When I bought it, there weren't really any other combo options around and nobody wanted to part with a model 24. Would I buy a combo again, not necessarily. I could take them or leave them I guess.
