Welcome to the forum and back to the loading bench. You have a great load there. I have the same rifle in 257 Roberts and it's a shooter.

The Remington 700 Classic uses the long/magnum action for the 257 Roberts. As a result, you can load bullets to the lands and not hinder the case capacity. I load the 115 gr BT to a 2.900" COL with RL22 for impressive speeds and accuracy.

Have several rifles/calibers, but next to work with is a Savage 110 Storm in 7MM-08 with detachable magazine. What might be maximum OAL? Never have reloaded for this rifle.
 
I am thinking of not using a bullet with an xtreme point in order to get as close to the lands as possible , but still fit in the magazine.
