I have a few blank 9mm's but a 9mm Folbert pin fire shotshell would compliment this display nicely.

Just got back in town.. I can't seem to find that Flobert 9mm. I've had it for years.
I'll keep looking though.

It's a great conversation piece why not keep it to remind people that this country is slowly going The way of Britain and this might be all that we'll have to fight tyranny.
Not really, we still got real gunz.

Convo started.
Most examples of large magnum cartridges necked down to .22 or .17 are primarily an exercise in metal turning simply for the entertainment value.
At gun shows I've seen .17 on 404 Jeffery as well as 50 BMG.
The "trick" is that to a point all the metal spinning is fairly conventional until the neck gets a bit thick. The number of operations alternating with annealing can easily number 20 or more. In the end most are fire formed after a final anneal in something of a "thing" chamber. This chamber is nothing more than a polished approximation of the desired shape in a piece of mild steel. The actual firing is minimal pressure to expand the case. In some techniques a projectile isn't even used. The pressure retained by a simple orifice.
A safer but les expedient method would be hydraulic pressure.
Sorry to state the reality of the matter but over bore capacity is well understood and even with recent powders that P.O. Ackley and Bob Hutton didn't have in the 60's any case much larger than a 22-250 is overbore capacity for .17 or .22.
Today's gun steels may be tougher than when the Winchester .264 magnum was introduced, and slower burning powders are available but there is nothing that can stop rapid throat erosion in an overbore capacity chambering.
It is kind of fun to walk by a table at a gun show and see a 50BMG necked to .17. It still gets a smile from me.

I have a smooth looking hollow point for the .50 as well. This is just a reduced head .500 SW magnum.

I got a spent case you can have. And can take your pick on 660gr or a 800gr projectile.

Or if you got more money than common sense i may consider parting with a raufoss round. But that would cost you!
