Really hope the "crush ribs" work for you... even if they do not there may be another .451/.452 product on the market in the near future that might really solve the problem...

I did try try to mic my barrels this evening when I got home from school. The only conicals I have on hand is some 50 cal 320 REAL's that outahunting sent me several months back. I mic'ed them the bottom ring was .459 and the top was .504. I set one in my Remington and thumb pushed it down the barrel - it slid all the way to the bottom, so I thought ok I will try the tighter A&H - it did require the ram rod to get it started and down into the barrel it was slighly snug but really like loading a PB pulled it out and tried the see the land marks in the lead - could not really tell that it had been loaded - so all I can tell you is my barrel land to land is slightly larger than .504 -.506 is probably right in the ball park...

not much help
