Interesting reading and photos.  Some are scary how bad they are.

Interesting read. When I built my first rifle I chambered it with no throat at all thinking it would be a good thing. Maybe I need to get a throat reamer. I never did have great accuracy...

no throat ....there was a similar system used by adolph neidner ... with some success ... but he used a bullet about 90 per cent bore rider, and 10 per cent groove band at the base ....

...and dr. mann used basically bore riders in his tests ..... not sure that is much of a recommendation, just an observation ....

my opinion is that bore riders are a good way to get 2 moa, and so are very popular because that is all most of ( us ) people need ..... below 2 moa the best system  is apparently still subject to debate and experimentation .
