Dave probably nailed it with the 25-06 suggestion but I?ll throw the .260 Remington in there if you aren?t stuck on .25 caliber. 85 Or 100 grain for yotes And 120 or 140 for big game. With the way components are becoming, I don?t do anything that can?t be formed on .223, .308 family, or 30-06 family of brass. KISS!
