Does the form of the rifling grooves have any impact on the performance of a gun? I'm NOT reffering to classic rifling vs. polygonal, I'm talking sbout the intersection of the grooves which is commonly rectangular but could e.g. also be V- or U-shaped.
And btw, are there any contemporary handguns that feature other than "square" rifling grooves? (Again, apart from polygonal rifling)
