Two HOT .224 cartridges
A couple of my friends shoot and are quite happy with the .22-6mm Remington, a cartridge that's very nearly (but not quite) the same as my .220 Howell. They've both asked me to compare some ballistics of our two cartridges. Somebody in one of these forums asked the same thing (I can't remember...- Ken Howell

.220 Howell vs .243 Winchester
One of the Good Guys on another board asked me to compare the down-range performance of his .243 Winchester load and a typical .220 Howell load. It occurred to me that some of my buddies here may be interested in the same data, so here they are. bullets — .220 Howell, 75-grain A-Max — .243...- Ken Howell

.220 Howell — reamer dimensions
Several shooters with new .220 Howell rifles have been having trouble getting decent varmint accuracy from these rifles. Trouble-shooting by a top-level bench-rest barrel-maker and rifle-maker revealed that (a) the rifles weren't properly bedded and (b) the chamber throats were so long that a...- Ken Howell
