Is anyone familiar with a particular bore spec for shooting solids? Lawton used to make barrels with a particular bore/groove profile as an option for shooting LRBT solids, but I'm not aware of anyone else doing something along those lines. Was it just a tighter or looser bore diameter? They were obviously working directly with LRBT and Cheytac at the time, and since more or less all parties involved are no longer around there's a dearth of information available. I've shot solids out of "normal" barrels quite a bit with mixed results, which just got me thinking...
