That's what I want.
I have no experience with the .35 Rem. but what I've read says it's superior to the 30-30.
With the LeverEvolution ammo it can reach out there.

If Marlin will bring out a similar new cartridge in .35 cal I'd jump all over it.

That seems to be right:
No, the round that made a difference was Marlin’s second most popular in this rifle: caliber .35 Remington. Remington created this cartridge in 1906 for their then-revolutionary Model 8 semiautomatic hunting rifle, and in 1952, Marlin began chambering the Model 336 for it. Throwing a 200 grain soft point bullet at 2210 feet per second, it generated 2170 foot-pounds of energy. With a 170 grain bullet at about the same speed, the .30-30 comes up short by comparison with only 1860 foot-pounds of energy.
