Actually according to Alliant's info 59.5 gr of RL-15 is the top/max load. See this link:

My 35 Whelen(Rem 7600) likes the Hornady 250 gr SP with an appropriate charge of RL15 and measured velocity is 2600 to 2650 fps.
The first 3 shots measure about .75" center to center.
I actually load 60.0gr of RL-15 and notice no ill effects. This may be too much for your rifle and would be wise to drop the load by 10% and work up to it.
Good Luck
