So what information has been shared to date?
I don't see any statistically verified data. I don't read any theories as to how the forces involved when seating a bullet interact with the IB process.
All I've read so far is a whole lot of how it should, would & could &, how wonderful & beautiful it is.
I never said I would never buy one, nor have I said that the thing is totally useless.
We'll see what comes off in the wash, for now though, there's nothing I've read which tells me I'm missing out on anything.
