Kimber, Remington, Winchester.
Tikka & Sako lite contours have much more mass than a #1 or #2.
Thus, the reason Tikka & Sako chose those profiles over going super lightweight.
In the post you shared, my point is perfectly demonstrated.
These are both factory Tikka's and both show a larger group shot between cold and hot.
This will be exaggerated with a thinned barrel, such as a Kimber!
#7 is what I see very often.
The thin barrel is heating up, and changing the point of impact.
This is proven when a 10 round consecutively shot group measures 6”.
And a 10 round group, cooled between every 2 shots measures 2”.
This has been repeated many times with several rifles with #1 & #2 barrel profiles.

Thin barrels like kimbers only shoot well for ~3 shots.
I use a magneto speed barrel cooler to cool between shots when at the range.
Also, I used a dremel and made a nice 0.100''-0.200'' of clearance between barrel and stock channel.
Marshmallows play dough for kids. Cleans up better than clay.
I shoot 2-3 shots and then use a Magneto Speed barrel cooler. Usually I do 10 round groups for accuracy tests and zeroing rifle scope.
2 part marine foam that you mix and then pour as liquid in the stock. Then it expands, and cut...
I agreed with this. Undo the action bolts, place action in stock, make sure recoil lug is against the back wall, snug the front action screw, put in rear action screw loosely, torque front screw, then torque rear screw.
I've also glass bedded Kimbers and seen the groups cut in half.
Lastly...
Completely False.
Go buy a Kimber mountain ascent, and show me a respectable 10 shot group shot consecutively with a can on it!
That same rifle will print great 10 round groups if allowed to cool after 2-3 shots. If 10 shots are shot consecutively, then the 10 round group will be 4-5X larger...
I'd run 1/2x28.
Pencil barrels will never shoot good with more than 3 rounds at a time. Get a barrel cooler from magneto speed.
I have a kimber at 19'' and it shoots 10 shots, 2 shots then cool between, under 1.5''.
