Danny,
They say it's the length of the bullet and not it's weight that's the limit for a twist. If you already have the 64 gr Win bullets then give them a try.
The 63 gr Sierra would stabilize in an old 222.
Don't rebarrel the rifle just to shoot a big game bullet out of a small varmint rifle. Either use the 222 for pests as it is or sell it and get a bigger gun.
