i was looking at the 700 and the 770 they have both in stock and in all the calibers i would like . i want a 308 whats a good price and what models is the best . and what calibers are the best. is a 308 the best for long range knock down or will a 243 do just as fine? they were all in a black synthetic stock witch i liked the only thing was to deside on a caliber. i will never shoot the gun so it really won't matter much but i really want one .
