I read once about the 30-378 necked down to .22. The barrels lasted around a 100 rounds. I checked out the 30 to 22 sabots in a 300 win mag, could get a 69 grain going 4800 fps but foot groups at 100 was the best it would do. Anyone shot the 55 gr. 30 calibers from JRP custom bullets ?

HOW ABOUT THE .22 EARGESPLITTEN LOUDENBOOMER, 105 GRAINS OF POWDER AND ONLY 4600FPS. TALK ABOUT MUCH ADO ABOUT NOTHING.
IT WAS A .378 WEATHERBY, NECKED DOWN.

It wouldn't matter if you necked down a 55-gallon drum to .22 - you'd only get 4500 fps or so. You can only move so much gas down a .224" bore in a few microseconds, all the rest is wasted or used to burn that bore.
Also, to keep from making the thing a bomb, the powder would have to be two steps slower than Kingston briquettes. And THEN there's the problem of the bullet. They have an annoying tendency to simply vaporize when they're spun that fast, booted that hard and heated that much.

It is possible to increase the gas speed above 4700 fps, but to do it requires much higher chamber pressures and temperatures than our rifles and reloading components are disigned for. More powder at sane pressures just allows heavier bullets to be pushed to the same top speeds.....

Excuse me, I suggest you go to www.reladersnest.com and look at the fastest round on the site. It is listed on the home page.
When it comes to velocity in a 22, the 22x243 M is the king of 22s right now and has been for many years.

Rocky,
Your post had me laughing pretty good. Next thing you know somebody is going to try making a case out of a 55 gallon drum and necking it down to .224. I think I'll stick with my .220 Swift for the upper end of the .22's and sleep just fine at night.

Psshhaww, a 55 gal drum necked down to .22 is nothing. You ain't serious until you neck it down to .17 cal. Then the pros go even farther with them real expensive and hard to find .14 cal pills.
