The 35 rem is 1.920 case lenght . Your limited to 1.80 ain't you. Get him a h&r or t/c in a 45lc or 44 mag or 357 mag that can be rechamber to a 357 maximum. http://www.bellmtcs.com/store/index.php?cid=121
The 44 and 45 with a hotter ruger loads in a rifle can reach close to 1900 and 1800 fps for each . That will get you out there to 150 yards atleast.
