Your 375 looks virtually identical to mine. Gloss action and barrel, green/black stock.
My only gripe with the Bull Bag is that if you're not careful the V hugs the stock so well that you can torque the stock if you need to move the rifle "just a bit" to get on target. If it's not lined up...
Cory Jacobsen did an elk hunt there, and Randy Newberg has done sitka blacktail hunts.
Both have reviewed what gear did - and did not - work for them.
I'd search out those videos and podcasts for some tips.
I bought a spring from this seller:

I would suggest the 3# one, as the 2# in my 7400 is about 1.5 pounds.
Not Weatherby.
"It was developed by Rick Jamison in 1997-1998 as proven in a 2005 lawsuit Jamison vs. Olin Corporation-Winchester division.[2] Jamison was given 7 patents on the cartridge design. U.S. Repeating Arms Company used the same concept and the same base case in creating its even...
I use stainless media for brass, and ultrasonic cleaners for car parts, gun parts and other items.
US is great for parts cleaning but just OK for brass unless you leave it in a long time.
I would then bed the action. It's not much more work than just doing the recoil lug, and then it's done right.
Accumarks are easy, as they are meant to be free floated, and the barrel channel is wide enough for some tape to center the barrel.
Weatherby.
I would have voted for Remington, but that company is on its 3rd recent life, and we have yet to determine if they're going to be any good.
Unfortunately it really depends on when the rifle was made.
26 inch factory barrels for all of these.
I have a 24 inch custom which has shot 160AB factory loads at 3020fps. However, they no longer make those loads so my couple of boxes are hoarded for that rifle.
There was a guy on LRH looking for 270 WbyMag cases, should you want to sell.
7mm Wby cases are not difficult to find. As I detest the idea of reloading one round in another so close in size, if it were me I'd swap them.
Then again, I probably have, um, too many 7mm Wby cases.
The slow load is...
I still have my Shooting Chrony Beta Master with all the accessories in case I ever need it, but sold my Magnetospeed.
FYI, I use the iphone app exclusively to arm and trigger the LR.
Labradar, external battery pack, JLK external trigger with magnetic mount.
I also purchased a "sight" that mounts via the top screw of the Labradar to use instead of the tiny notch in the top of the unit.
You can use the tabletop base or a tripod to hold the Labradar. Either works, but your...
Short answer, no.
SAAMI specifications call for the freebore. As a SAAMI-compliant manufacturer Winchester would have included it just as Remington does in its Weatherby chamberings.
