My very first centerfire rifle was a .243 which I sold more than 40 yrs. ago, I have had a .257 Roberts for 30 or so years now and like it very well though it does not get as much field time as its big brother my .35 Whelen. Both are great classic cartridges created by two men what were some of the most knowledgeable of their era.both have had times when they were more or less popular but both have stood the test of time.
