| I'm looking at 6mm barrels and I see that there are options for anywhere from 3 to 6 grooves in the various twist rates. What advantages/disadvantages are there for more or less grooves? |

Stability, friction, and fouling are the talking points I seem to remember reading before. I believe the dimensions and quality of the grooves are more important than the number. I've fired some 2 groove Springfields that would cloverleaf until they heated up and I'd almost bet there's a few "micro-groove" type (9 grooves?) barrels that shoot very well. I stick with 4 or 6. |
