I've never shot the Rossi, but I have a savage.
If your asking about he round in general and not that specific rifle..
It shoots great.
It feels like a stout load when your shooting under a hundred yards.
sub .22 size with a .243/22.250 punch.
I've shot a ways beyond, but wind really starts to play a factor at 150+yrds.
Not saying greydiggers @ 300yrds is unrealistic.. cause it's not
but I've also had a heck of a time just over 150 with a lot of land features and some strange wind. You can see the bullet get pushed around through the scope on a sunny day with some wind..
