Cast bullets and the .35 Remington?

[Mr. 16 gauge]

Hey all;
I have a Marlin 336 with the microgroove rifling. Bought it a few years back (used gun), as my granddad had one and I bought it for sentimental reasons (his deer rifle was the first centerfire rifle I ever shot).
I've been thinking about loading cast bullets for this gun; I already load cast bullets for my Winchester M94 in .30/30. While checking my Lyman cast manual, it only list loads using pistol powders such as SR4756, green dot, ect. The reason is to limit velocity because of inaccuracy with the microgroove rifling.
I'm thinking about loading the RBCS 200 grain FP with gas check in this caliber.....my question is(are): has anyone loaded cast bullets for the .35 Remington? If so, what loads/velocities have you found to be most accurate? Also, will using a gas check bullet negate the negative effects of the microgroove rifling, accuracy wise? I would like to be able to load with rifle powder to a velocity of around 1900 fps (jacketed bullet velocities) if possible. I currently shoot IMR3031 with cast bullets in my .30/30.
Thanks in advance.............
