What does it all mean?
Put a lump in the middle and a thing on the end.

The theory is sound enough and the computer simulation stuff is interesting enough to sell a lot of people. The idea is far from new but the concept of computer modelling and tuning is. When I start losing quite a bit to guys with things on their barrels I may become a convert. Until then I'm happy with the way I'm doing things now. Regards, Bill.

Sounds like a really techie explanation of " adding mass at a given point on the barrel reduces vibration ".

When I see it showing up at BR matches, I will be much more interested.

For what it is worth I don't think that they allow barrel weights or tuners on centerfire BR rifles.
