I recently bought a Wby399 in 25/06. With just a little trigger work it is shooting under an inch at 100yds. It came with the target in the box that measured .943". I haven't been hunting since I bought it,but I have no doubts that it will get the job done. Whether the quality of your earlier rifle is better,I can't say; however, if yours shoots as well as mine you've got a winner!
GOOD LUCK and GOOD SHOOTING!!!
