I would imagine some more recoil, but I doubt you'd notice. It gets higher velocity with a new blend of powder and lower pressures than you'd get loading it up yourself.
A slow burning powder that gets the velocity up will have more of a push than a sharp jolt.
Plus the velocity numbers are from a 24" barrel too.
My 94BB pushes a 250gr bullet, in front of a healthy charge of RL-7, to 2130fps from a 20" barrel. The 30-06 is rated to push a 250gr bullet to 2200fps from a 24" barrel. My 94 kicks less than my 30-06 and weighs at least a pound less and does not have much for a recoil pad either.
I'd imagine another 150fps or so from a 30-30 will go unnoticed at the shoulder.
Tempted to get a 30-30 lever just to try this stuff out. My one Win 30-30 (1866 Centenial rifle) is a collectable and I don't want to shoot it.
