One more time.

Both the bullet makers and those against the use of monos could post names, credentials, contact information, business relations/interests, documentation and proofs.

Actually, I don't need to do any research, the Prospective Mono Shooter does.

As a matter of fact, it is possible we might be able to get a company or two to engage the members here on this Forum on this topic. I'm working on that. If you have some specific questions you'd like answered or addressed, PM me and I'll be happy to forward and see if we can't get this done. I don't want to be too optimistic, but possibly this forum can be the place where both sides of the issue can present their data and documentation in an, imagine that, open forum.

This Forum has high standing among companies and shooters, and with members such as yourself and others who have extensive double experience, seems a perfect and natural place to do it. Possibly John could form a sticky on the subject.

On a separate note, what sort of experimentation could be done to replicate OSR without ruining a fine double?

I'm thinking a .458 barrel could be turned down to a wall thickness equal to a '20's-era double {or thinner} fitted to a cheap Mauser action and shot with mono's. Granted, the steel alloy and rifling dimensions would be somewhat different to the old double, but a workable duplicate could possibly be fashioned? I know a gunsmith who would very likely be interested in building such a test bed. This would not necessarily duplicate harmonics, but should address the issue of the "snake swallowing the egg" at the very least.

Possibly a collection could be taken from members for the materials and gunsmith fees, ammo, etc. Couldn't cost but 500 or 600 bucks or so, since the action wouldn't need feed work as a single shot and could be fitted to a cheap plastic stock. Sights wouldn't even be needed. Heck, the bullets would cost more than the "gun".

Ten or so guys kicking in $50 or thereabouts would do it I think. As you say, I am not a double owner, but as a gun nut {sorry, crackpot} it would be worth $50 to me to see the project completed and documented. Barrel dimensions could be taken throughout. Maybe a bullet maker would be willing to kick in also.

Possibly some other experiment could be put together as well if the above idea doesn't meet muster in your judgment.
