I have been looking at the .17Rem caliber and was wondering if it can still be an accurate little round for 300 yards without a short barrel life ? The reason I ask about barrel life is that its moving at 3800-4500fps, How many rounds can I get out of a barrel? I have shot a few at 50-100yds but never owned one as of yet [17 hornet 17rem17hmr17fb]. I was planning to build one from a savage .223 and shoot the 30gr bullets in a 17 rem.cal. with a 9 twist for prairie dogs , groundhogs and a few tweetybirds .
