Combination guns are frustrating until you spend a lot of money. I have owned several made by Savage, A springfield scout, a Valmet-Savage, a Valmet, and a Brno. All of the Savage made guns had problems with function and regulation. The Valmet guns functioned better but were very poor to handle an they did not fit me well. They were clumsy to use with rimless rifle cartridges. I now own a Heym in 16 ga. over .222, and a Merkel in 16 ga. over 7x57R. They work reliably and are very accurate, they fit me and feel wonderful to handle. But they cost about four to six times what the others do. It requires fine engineering and hand craftsmanship to make a combination gun that works well. You really do get what you pay for.
