SNIP
Assuming a high BC bullet in a thick sabot AND an accurate load, I guess it's possible. I'd like to see something like a 208gr A-Max (.308) in a sabot at good initial velocity. If you could get that combo to shoot accurately then you'd be good to go.
Sorry, they are made one at a time on a cnc lathe to fit my 1:14 twist barrel.
