Has anyone built one of these yet? Could just use a 223 rifle as a donor. Seems like this would surpass the 223 AI pretty easily. Could use the 204 Ruger reamer w/live pilot and use a 224 pilot instead of a 204 pilot. Hornady could do die modifications. Should be able to hit 4000 fps with a 40 gr bullet easily. Anyone have any info or first hand experience?

A friend of mine, Warren Brookman, "came up" with the .20 Practical which is simply a .223 necked down to .204.
We are members at the same rifle range and Warren seems to love to challenge the, or should I say, push the envelope in the search for simple solutions to anything dealing with 'shooting'.
If you go to 6mm BR web site, http://www.6mmbr.com/20Caliber.html, you will see an article on the .20 Practical. just click on .20 caliber info page.
I built one of these and it is amazingly "simple". you take .223 cases and a Redding or RCBS bushing sizing die and in a couple of steps you have bushed down the .223 to .204.
I am pushing a 39 grain Sierra Blitzking to 3,950 fps. A 32 grain Hornady V-Max goes out at 4,200 fps.
The .223 brass is available out of the brass buckets at the range free and with the use of the bushing sizing die I make all the .20 Practical I can ever shoot.
This particular rifle turned out to be what I believe is a truly 1/2" rifle, that is every time I shoot it at the range it will deliver 1/2" 5 shot groups IF I do my part and the moon is in the correct quadrant.
The rifle started out in life as a .204 Ruger, so why the change - - - the Remington barrel had a large inclusion in it causing extensive copper fouling and since it needed re-barreling and with Warren to guide me though it I thought why not do something a little different, and yet relatively inexpensive. we used a Pacific reamer and a 3 grove Lilja barrel.

Yup what your talking about has already been done a long time ago. Matt's got it right it's called the 222 magnum. Considering the 204 is one of the best new varmint cartridges to come along in the last 50 years I don't know why anyone would want to improve on it. The longest coyote with mine was 385 yards and DRT.
22 B-R!!! Now you're talkin. For such a compact little round, the 22 Bench Rest can hold it's own against it's bigger cousin - the 22-250 with bullets up to 55 grains in weight. Run a 3 or 4 groove barrel with a 1-14" twist rate you would be very hard pressed to find a more accurate round and with ample velocity for long-range varminting....

Actually if you look at cartridge drawings of the 204 case and the 222 Rem Mag you will see that the 204 is actually a 20-222Rem mag Improved with the shoulder changer to 30 degrees and moved forward, the body is straightenned a little. So your 22-204 would be a 222 Rem Mag Improved (without any fire forming) and yes 4000fps with a 40 is possible, I built one a couple years ago and it's a great coyote gun.
