How many rounds can you stand to put through your 257? I was checking out the Weatherby site, lookig at ballistics. It says that the 87gr. only drops about 20 inchs at 500yds. That would make a heck of a varmint rounds. I have never shot a Weatherby round before, but i can put 40-50 rounds through my 300 Win Mag. With out my shoulder getting verysore.
