Agreed with others that humidity changes is going to be your issue. *If* you get dessicant packs in containers which are sealed enough to not get spent quickly (but not sealed well enough to be an explosion hazard) then you're set.
See here for velocity vs humdity testing...
140 g would definitely be heavier than I'd go, that will take up like half the case volume. I deer hunted for a few years with 129 gr ABLRs, OK accuracy (but totally acceptable for deer <200 yds) but great terminal performance. I only got like 2300 to 2350 fps, I wouldn't want to go any slower.
I built my elk rifle on a smaller budget, but very little I'd change with a larger one. Add on whenever can you like and you're still well under your budget. Could maybe even upgrade to a Tenmile 3-18.
I spent enough time working in chemistry labs for it to feel wrong to have powder and primers stored outside of flammable cabinets. Plus it's many state/local codes to store >20 lbs powder in a 1" nominal wall wood cabinet, per NFPA 495. Those are often also included by reference in home...
I don't think that's going to work well. The problem is going to be feed lip width as well as shoulder location. On my 3.56" mags I bent the feed lips to 0.475" which works well for my 284 Win and seems to be good for 7mm RM. But that's way too wide for 6.5 CM. In addition the mag crimp that...
Barrel #2 here is ~21" but really heavy contour (not mine): https://www.snipershide.com/shooting/threads/various-tikka-barrels-and-muzzle-brakes.7180881/
I've got a few of these for sale, brand new in packaging. Medium length, FDE. Looking for $135 shipped OBO each PP net fees.

Innorel / Articise tripod have been great for me. The CT70C I can shoot off standing, and it holds my heavy match gun no problem. Total weight with ball head is under 5 lb.
Since you don't care about standing, you can save a pound and use the CT75C.
Fixed the FOV numbers now, thanks Beetroot.
Multiplying the max FOV by min mag gave almost the same constant as the min FOV times max mag, differences due to tunneling I assume. So my 5x are base on the max FOV constant and 12 on the minimum (and therefore may somewhat underestimate FOV for the...
I'm glad I'm not the only one nerding out about specs! Not sure if it's the correct way to do it, but I just linearly interpolated between Min and Max FOVs (and it looks like my formulas for the ones you mentioned are consistent with the others). Edit: I'll recalculate by dividing by...
