[QUOTE="Michaeljcanoe, post: 301674, member: 1490"] I did read Mr. Lewis's article recently. But something on a related subject. My .17 Rem (standard neck) recently began putting bullets out there that weren't reaching the 100 yard target. (Berger 30 grainers with 25 grains of Varget). I checked for case length and for a burr to no avail. Gave it a good scrubbing and then shot at the 25 yard backer to find the smudges of a bullet coming apart (velocity has always averaged 3930 at the muzzle). The only thing I could realistically think of was extreme velocity causing destruction due to rotational velocity. Walt Berger questioned the brass. Then I got to thinking...I have loaded this brass many, many times and shot them relatively hot, never needing to trim. My experiences have been that this small brass just does not show brass wear. Began to suspect brass flow to the neck where it might be accumulating , the thickening causing a tight-neck condition. So threw those cases away and reloaded with virgin brass. Presto! Problem solved! This rifle/load combo has taken around 800 coyotes over the years and a bullet not even reaching the critter might be thought to be a miss. But checking things out on paper occasionally will save the anguish of a certain kill being lost. Montana Mike [/QUOTE]
