[QUOTE="ss7mm, post: 301057, member: 5"] My gun was one that Kirby was involved with when the testing of the width of lands/grooves was going on. I had a 3 groove Lilja and we finally pulled the barrel and sent it to Lilja for inspection and testing and it came back with a clean bill of health and a video tape of the testing, although it was destroying bullets. Kirby did extensive testing and evaluation and as a test he had Mike Rock build some barrels to his specifications as far as lands and groove width goes and I now have a 5 groove Rock built to Kirby's specs and it's happily spitting anything I feed it out the tube and down range. I agree with the performace level of the round vs. the 3 groove barrel and it's advantages but.....since I prefer a little more horsepower, I'll stick with the barrels configurations that fit within the guidlelines of what Kirby came up with.
