My .257 Roberts is a late 60's build, Springfield action, 25" #5 Shilen barrel and Pecan wood stock fully bedded. The load it loves is utilizing the Speer 100 grain spire points at 3010fps that will group under 1/2". I hunt deer and antelope with it and they have all been one and done. I don't shoot past 250yds and only take head shots with it. Yes, I've let critters pass 'cuz the shot wasn't there but the point being it does the job and I'm happy with the results.
