So, as .22 Mag is now about $14 per 50, or .28 cents per shell, I've been wondering, can I build 40 grain .223 that will go 1900-2000 fps, for less? Two reasons for the velocity...first, it's to mimic the .22 mag, and NOT blow up the target, possibly food, and second, less powder will keep cost down. I know there are fast loadings in the light bullets, but no idea if there's a reduced charge slow load. And, I'm not sure the small amount of powder will be safe, or reliable. Oddly, I don't care if it will cycle an AR, I have a break action to use it in, or I can just cycle by hand. Just starting my research, wondering if anyone has tried this, or has info?
