I think it's a dumb idea myself. Why are we trying to do so much with a .22 caliber bullet? next thing we will be trying to shoot 105 grain 22s with a 5 twist barrel. Where does the madness end?
If you want to shoot at very long ranges, don't try to do it with a mouse gun. Simple as that.
I think you should check out the 226 Barnes QT and with the newer powders it should do even better. Just saying. Cheers NC
