I'm thinking about selling my sendero. It's the older stainless fluted model. It has a mcmillan rem. bdl stock that is skim bedded. It has been accurized, 2# trigger, hart muzzlebreak and gre-tan firing pin & spring. It has about 50 rounds through it. My question is--what is a fair asking price for this rifle? BTW, it's a 300 win mag.
