take a good look at any early rigby in 7x57 or "275 rigby" and you will see a very ordinary action without a hinged floor plate ,a single - two stage trigger, military style bottom metal, the only thing you would change is the bolt handle to a "oberndorf -rigby" style and by that i mean the bolt is just a little closer to the stock than an original oberndorf sporter the rest of the gun is very straight forward most rigbys did not have trap grips or grip caps for that matter,no cheeckpiece ,safety stays the same ,no horn tip simple chechering pattern,if i had an intermediate action this is what i would build,,,and who doesent like a 7x57 ?......paul
