Tied the 35/40 to a chair and started with 40.0g Varget, pulled the trigger with a string and went as expected.
Next shot with 43.0 grains, no problems.
Next shot with 46.0 grains, was also uneventful.
I had refigured for a compressed load and got 47.2 grains, so I loaded this as a proof load as Q/L still showed it to be safe. Same results, no signs of pressure. When I checked the powder depth with 47.2 grains, it was still not a compressed load, so the case capacity of the unfired Remington case is greater than I originally figured.
The 47.2G fired case is on the left an unfired case on the right, the shoulder did move at least .010 on the fired case. I will need to refigure after checking water capacity as the fired case will have more volume. (see photo below on optical comparator)
After untying the rifle form the chair I fired one 43 grain round offhand and it was not unpleasant.

Here piggy piggy! (insert smiley here)
