If I did not already have too many rifles to get tuned up, matched to the "perfect" load, etc., etc., and if I had more greenbacks to my name, I would be all over doing a conversion to 338 Federal. I have never heard a bad word about the cartridge, and I really like those 30-somethings. I have a 338-06. a 35 Whelen, and a 35 Remington. Like em all.
