I suppose this is the right forum.

It seems to me that 4000fps is some magical barried that alot of wildcatters try to break. But it seems to me that the shells that are being used are nothing really special. 25-06's necked down to .22's and stuff like that. Why doesn't anyone go to the extreme and neck down a big shell like the .416 rigby's or the .460 weatherby, or just go the the whole way and neck down the .50BMG? It would seem like that would be easier than trying to over pressure the smaller shells.

At some point you reach a point of diminishing returns.
A few years ago some shooters built a .223-.378 Weatherby Mag.
They wrote a piece for Precision Shooting mag.
The barrel lasted about 95 shots before being toast.
The .224 cal. bullets were doing about 5050 fps. I can't remember if the bullets were self-destructing or not but I would think that they were. :eek: :D

Here's a link to another forum that I found where they talk about the
.223-.378 Ergensplittin Loudenboomer. :D

95 rounds is enough for me to say I don't really need that.
Thanks for your info, though.

Fast is not always good. Most ammo is more accurate below max FPS levels.

I just realized that I spelt barrier wrong. Moron.

I realize that speed doesn't bring accuracy. I look at it as one might look at funny cars. They aren't "better" either compared to the fuel efficient and safe cars that are available to regular people. But it does make me curious. Not that I will attempt at 5000fps or a 4 sec 1/4 mile.

It would be fun to try either one as long as I wasn't the one paying the bill. :D

Remember that the higher you go in velocity the quicker the bullet slows down. Look up in your manuals bullets starting at 4000 fps in the trajectory tables & see how quick those bullets are down to 3000 fps.

Oh I realize that, same thing with the funny car thing. They can only go 1/4 mile. I was just wondering for craps stakes.
