Not a wildcatter, but I suspect that there might be two obstacles to that project:

1. The bullet would turn into a blob of plasma in the bore from the heat of the powder burning. It would self destruct.

2. The bore life would be measured in tens of rounds. IMHO, you would make it a smoothbore really quick. Talk about overbore!!

Still, I'd like to chronograph something like that!!!!

I'm with Powderman on the bore life. This cartridge ought to be a real welding torch.

There are much "better" cases like 155 howitzer shell and some battleship or old nazi guns (800mm or so), you can make 500yard deep hole in rock, put barrel to it and of course aim it to the Moon (bullet would be make from "Black hole" substance) .. .
Jiri you sound like a real asshole but I'm sure you had your share of stupid questions for this forum so give me a break!!!

I believe it would take about 10 minutes for all the powder to burn out the end of the barrel after the bullet exits the muzzle. (grin)

It appears that 'bore capacity' is related to projectile size and what is overbore for a 52 gn projectile isnt for larger projectiles like Sierra 80gn VLD.

As projectile gets bigger program shows useful gains from larger cases where as with 'traditional' 40 to 55 gn projectiles no useful gains are available after about .220 swift size although small margins can be had from likes of .22 CHeetah etc.

I suggest you look at a fat case that can be shortened to an appropriate length, start with a design that follows the benchresters 'short fat case' concept, sort of like a large PPC. Doesnt matter how fast they are going if you cant hit them!

I believe a slightly shortened .338 Lapua Magnum case using aforementioned 80gn VLD would be pretty good for ultra long range varminting. Still to build it so cant comment on barrel life.

Like to hear others experiences of large cases with larger .224 projectiles.

According to my info,the 224 Clark is made off the 257 Roberts.Is this the one you are using,and if so,how in the hell are you cramming 60 grains of powder into it?Max capacity of the Roberts case isn't even 50 grains.

Last word was that he went to the range to do some load testing.

Haven't heard a word about the project since.

All so went that with my clark up to sixty grans there was a lot of FPS per grain but when we went to 61gr there was only a 10fps gain we had reached the limit of the case and started to see signs of pressure that was not there with the sixty gr load Have a good nite: Coyote slayer

I believe many years ago, just for research purposes, some organization necked a .20 mm cannon shell down to .224. The results were very little velocity increase over a .220 swift and a barrel life of 4 rounds.

If this sort of thing sounds smart to anyone, go for it. Just don't expect anything for your trouble but a good tent peg.

Don't know if he got any chrony readings off it though...

As yorick pionted out, I have put a .22cal bullet in a .22/.30cal sabot & then put that in a .30/.50cal sabot. I have not shot it, but it does look neat :-) I'm guessing velocity at or around 6000fps, but you would be lucky to hit the broad side of a barn at 25yds. There is way too many variables to throw off bullet/sabot concentricity.

I'm running a little 'project' soon and I will let you guy's know the results ;-)

I seem to recall that barrel life was pretty short--less than 200 rounds.

If someone actually has the money to waste on this type of a round then I need to get to know them and try to get some for a few more practical projects I have in mind.

No flame intended to anyone!!!

I remember reading about a wildcat in a norwegian reloading manual, called 22 Eargessplitten Loudenboomer Not 100� certain of the spelling). This was a .378 Weatherby necked down to .22, and they said it was completely useless. Had no barrel life and the velocity wasn't all that great...
