If barrels were more consistent as far as bore size I think there would be a good possibility of that happening . Right now there seems to be quite a variation in bore size between different companies . At least there is between my T/c , Knights , whites etc with the Whites being the most consistent .
I personally would like to see a Lehigh made for my .451 whites .
They also have the best twist for each caliber in my opinion .
.504 is 1:24 , .451 is 1:20 , .410 is 1:16
