ok so ive just been watching making the cut, and it was the episode on marine scout snipers.. these guys are working the bolts on their rifles as fast as a damn pump action..

im curious if this is purely because of the volume of use their rifles get, that the bolt softens up a bit, or do they swap out a spring for something with a little less tension to make the bolt work easier?
 
id imagine the bolt would free up after use. my r700 had 10 rounds through it when i got it and it was really tight. its still stiff but its gotten quite a bit better. also i find that after i oil it its smooth as butter but you put 60 or 80 rounds through it and it tightens up a little again

There are a number of tweeks to get a R700 bolt to cycle well ,smooth clean.
(fast is smooth,smooth is fast)
FP spring ,trued and polished surfaces (easy start is your cocking piece and ramp)
Some "tight" guns do "wear" in to feel smoother but modifications prove best results.
There is a decent book called "Accuratizing the Factory Rifle" that has some ideas but there are some good articles that can be found on the net.
Also familiarity (practice) helps.

Working it, and a little grease on the camming surface of the cocking mechanism at the rear/underside of the bolt helps.

Just think of it as a 303 in reverse :)
 
I would just figure these guys are
a: very stong, so it looks like absolutely no effort, because for them it's practically nothing
2: spend a LOT of time doing exact same motion, so excellent muscle memory
C: using very well made rifles with the best smoothest actions available, which have been worked in with LOTS of rounds through them.

Some combination of the 3 likely accounts for most of it.
 
IMO the actions; receivers and bolts must be relatively hard in exces of 35 HRC and honed with super fine grit (600 and up) to be very smooth. Soft metals will wear down easy each other, gall and sometimes even seize to work alltogether. Pre and post war Mausers and Manlichters with proper carburizing and heat treading so the "skin" on metal is as hard as glass are notably the slickiest to operate. No amount of super acurate CNC machining will replace polishing and honing the working parts by hand in right places.
 
High quality stock give better "bolt control"

I have a lowly Remington 700 VTR which was fired 500 times and dry fired around 2000 times and my rifle's action is getting seriously fast!
The biggest improvement came when I changed the flexy plastic stock for a high quality AICS Stage 2.0 stock!
Having a rigid, ergonomic stock made a huge difference and I feel that I have much better control of the bolt with this stock.

My new Remington CDL SF has only been shot 110 times and is extremely tight but is getting looser each time I shoot it. (It's a stainless steel rifle and I might be stickier that CM steel since stainless steel is softer than CM steel)
