so ive been doing some reading about ways to decrease the slop in the bolt and came acrossed the ptg bolt bodies and also the bolt bodies from sharp shooter supply. my questions are do either of these help decrease the movement. is one recommeded over the other and is this really worth it to do this upgrade. the rifle i would be doing this to is the 110 tactical left handed in 6.5 creedmoor. any advice would be greatly appreciated as im driving myself crazy trying to find info about this.
Is the "slop" and "movement" you're referring to, the clearance between the bolt body and the receiver raceway?
Assuming that's the case, you'd need to measure front/rear ID of the raceway with gauge pins to determine your smallest ID, then select a bolt with the desired clearance.
Clearance desired should depend on the use of the rifle. A hunting rifle needs adequate clearances so that a speck of dirt or grit in the action isn't going to cause a malfunction.
To do this the "right" way, you would ream the bolt raceway to a consistent, oversize dimension and then use the appropriate bolt body.
So, short answer to your question is "yes"- but you need to be able to take the necessary precision measurements, know the clearances needed- and be realistic about what you might gain.
The floating bolthead on Savages compensates for minor misalignment. Things like bolt tilt are a consideration on precision rifles, absent other work being done it's not likely to show you a return at the target.
JMO. YMMV.
I have used multiple from ptg, they do help some, not as much as you probably want. Also, every action I have measured the rear of the bolt race is a larger diameter than the front. Unless you open the bolt race there will always be considerable slop because of this.

I’ve switched out the factory bolt body and bolt head to PTG on a couple of PDog rifles. They took out the slop. I did notice some slight binding with one action that smoothed out with time/bolt cycles. But these were actions fitted with a single-load ramp/magazine for bench shooting and not exposed to a lot of dust and grit. Not sure I’d recommend on a hunting rifle.
If you do want to order one do yourself a favor and don't get one of the fluted ones. You can also use telescoping gauges to check the size. Trying to remember if our gauge pin set goes to .700 or not.
The way SSS flutes his there is no drag. Best to just keep a smooth bolt.
The Dunning-Kruger effect is alive and well.
Don't fix it if it ain't broke!!
Oz never gave nothing to the Tin Man, that he didn't already have.
Reducing the slop also reduces the float.....the thing that makes Savages shoot so well. With factory production tolerances being what they are, the "slop" is there for a reason. I've installed several oversize bolt bodies only to find that accuracy suffers. This is a case of applying Remington technology to a Savage.......it doesn't work. But you can apply Savage technology to a Remington and it will.
