35 Remington flat nose bullets drop like rocks as it is out past 75 yards, so I go for a decent amount of speed. My 37 grain H335 load is bumping right below 2100 fps and the 31 grain RX-7 load right at 2000 IIRC. Neither are absolute maximum loads pressure-wise, but are close and definitely near the point of diminishing returns regarding the pressure/velocity curve of a 208-grain bullet in a 20" barrel. I don't like punishing my ears when hunting, my shoulder, or my rifles and brass, so when I get up near the top and find a load still groups well, I tend to quit while I'm ahead. If I ever feel the need for more power in a .35 I'll step up to a 358 Winchester...or the Whelen...rather than hot-rod the little Remington cartridge.
Six to eight inches of drop at 100 for a 50-yard zero and 500 fps loss starting from 2100 is something that you definitely need to take into consideration when hunting, even at relatively close range. If you're used to "modern" ballistics where you don't even need to think about drop tables until at least 150 yards, much less losing 25% of your killing power at a range most of us could throw a rock, it's an eye-opener. My 300 Blackout shoots heavier bullets much flatter. BUT, the 35 is a hammer and a half when you need it, cuts through light sticks and heavy grass without deflecting much at all, and the 336 is about as handy and fast a rifle as has ever been made. Great combo for tight, fast, heavy work.
Shot a few groups while chronographing some 3031 loads for the 336 35 Remington. Having shot this powder in this rifle before I started with 36 grains and stopped at 37 grains. Best accuracy showed at 36.5 grains. LEE 35-200 RF pc'd, aluminum gas check and sized at .35925. I didn't adjust scope from shooting 180 grain Speer loads. Did not like 37 grains. If I can get consistent 3 shot groups like this target shows the first three in shot order I may have something.
