.35 Remington - 39 grains;
.35/.30-30 - 34 grains.
Now, when a 200-grain bullet is seated to 2.55" overall cartridge length to feed in a Winchester 94 in the .35/.30-30 case, its base is 1/3 the way up the neck, so I took another measurement, this time filling the case neck with water and carefully squeezing out the excess pressing a bullet to the crimp groove in the fired case.
That result was 37 grains.
So, I determined that using .35 Remington load data was OK as a guide as long as I stayed a grain or so below maximum loads.
This has worked well in actual practice for over ten years and I haven't blown up anything.
