If so , what do you think of it ? For some reason the idea intriges me........a 22/6mm , Clark , 220 Howell or the like with a fast twist barrel and shooting the heavy match bullets......... | ||

I had a 22-284 for a while. Jimmy Knox made me some 90 grain bullets. When I got the velocity that I wanted the bullets came apart. Above 3600fps they went all over the place. I set the barrel back 2 times in 1100 rounds. I used an 8 twist barrel. Too much trouble for very little gain if any. Butch | |||

Here's a thought...maybe try the .300 WSM casing necked down to .22? It would be interesting, although erosion would be a killer. Ever heard of the Eargashplitten Loudenboomer? It was a old test done a while ago, a 50 BMG casing necked down to .22. I think they used 230 grains of a unknown ball powder and a 50 grain bullet and the barrel was completely devestated after 8 rounds. I thought it was kinda funny. They got almost 5600 fps with a 48" barrel. "Molotov Cocktails don't leave fingerprints" -Dr. Ski | |||

No, the Eargashplitten Loudenboomer was a necked down 378 or 460Weatherby. (Ackley handbook Vol.1) AllanD If I provoke you into thinking then I've done my good deed for the day!

A friend has been using just a 220 Swift with an 8 inch twist to shoot 80 grainers. I think that anything beyond that may be reaching the point of dimenishing return. I have seen a 22/06. He had to be real picky which bullets he shot due to the bullets coming apart over 4200 fps. RELOAD - ITS FUN! | |||

224 Vais. 6.5x55 necked down and fireformed. You can skip the fireforming and call it something else. 80 grain VLD at 3800fps | |||
