Wildcat idea

[Longbranch]

I don't know if this has ever been done... I'm not a wildcat guy but I've been thinking about this lately...

A .260 Remington (120 grain) bullet in a .223 Remington case. Has this been done? I know the 6.8 SPC is close, but I'm thinking of using a bolt/action that can use the .223 case.

-----

One other question about reloading and powders...

Can different powders be used in the same case? My thought was put a slower burning powder in first (1/2 or 1/3), then a faster burning powder on top. Kind of like gears in a car... 1st gear is more torque than horsepower to get the thing going... once there's momentum, shift up. Make sense? Been done already? Is it obvious I'm a rookie with this?

Thanks for any help.

look up 6.5 TCU.

mixing powders is something i wouldn't try at home.

In the world of wildcatting, it's ALL been done before. Some people might change the length or angle by a unit or two, but it's still not altogether new. Might not have been published, or seen by the "designer", but guaranteed they will come out of the woodwork when someone claims it's new. It gets particularly amusing when some "patent troll" patents their invention.

"Duplex" loads have been around a long time. They typically consist of a slow powder (usually blackpowder) over a very small amount of fast pistol powder, held firmly in place at the bottom near the flash hole by a full, often compressed powder load. The fast powder helps to completely burn the slow. To make a long explanation short - if you have to ask what it is and why, don't do it.
