Fukiyaman posted an interesting post about 2 years ago about the barrel "slimmer" . I think posts like this sometimes go unnoticed . I would like to know if anyone has found this way or a simple and cheap way to taper a barrel and their results . The aboriginals taper their bores and seem to have increased pressure ..also I've seen the post about magnets , any actual speed increase/Chronograph proofs? I've also looked up on http://www.magnetic.webege.com/youtube.php a magnet linear accelerator , real simple just wondering if anyone could tie it in to a barrel/pipe with the magnets . Also fukiyamans picture of the releasing barrel plug look real promising ..anyone have ideas thoughts about this ?? Thanks !
