The 336 is designed for loads in the 50,000 PSI range. 41.5 works well in my gun, as well as the same charge of 4895. The 35 Remington is a great cartridge in the Marlin.
So what do you think that load might run in PSI?
Someone on this forum ran that load thu QuickLoad computer program, QuickLoad said that the pressure would be around 42,000 PSI. But remember, that's a guesstimate not an actual pressure test. At any rate, it is well within the Marlin's limits.
I check my loads on the chrono and try to run between 2200 and 2300 fps with 200 gr bullets in a twenty inch barrel.
