Firing Pin from "Old Style" bolt & "New Style" bolt body

[GrpThrpy]

I just bought a brand new 110 Precision in 6.5 Creedmoor and am having nothing but bolt problems, including failures to extract and problems chambering.

Both those problems are being addressed but overall I'm really miffed that my $1600 expense came with a bolt assembly that looks and functions like especially compared to the one in my 110 Hunter in 30-06 which is smooth as silk, super shiny and half the price.

The folks at Gun Shack have a $40 new-style stock replacement bolt sleeve that I would love to swap for the rough and ugly one that shipped with my "new" rifle.

Can anyone tell me if the old style old-style firing pin assembly will fit into the new style bolt body?

Your rifle should have a new style firing. Unless it’s <2019. But yes, it will fit using all the parts. Regardless, neither the firing pin assembly or the bolt sleeve are the cause of your issues. However, there is no harm in replacing the Bolt Sleeve for aesthetics. Though you’ll need to headspace. The reason your 6.5CM is having problems where you 30-06 is not, is because instead of the 30-06’s long, tapered case, the CM case has nil body taper.

You need to replace the Extractor bearing ball with a larger .140” ball. (I also use the modified Extractor). Also, file a little more bevel in your Ejector face clocked pointing to the Cartridge. Like the photo below.

Thank you for replying David! I really appreciate your explanations and especially the tip about beveling the ejector face. I think I can handle that myself but I’m not 100% sure what you mean by …

Though you’ll need to headspace.

… but it sounds like I may need to go to a gunsmith. Is that the case, or do you mean I just need to break out my headspace comparator and take new measurements?

Different Bolts, Bolt Sleeves & Actions are not identical lengths. They can vary several thousandths. The Headspace is the space between the length of the Chamber & the cartridge. We use Headspace “Go” & “No Go” Gauges to set the headspace via threading the barrel further into or out of the Action & securing by torquing the Barrel nut. It’s one reason the Savage is different from many other rifles as barrel replacement is quite easy & can be done by any DIY’er. With rifles like the Remington 700, the barrel is shouldered. A good Lathe & tooling, in addition to a greater knowledge of gunsmithing is needed to replace the barrel. By replacing the Bolt Sleeve, the headspace may not be the same and would require setting it as I outlined above. There are many, many blogs, videos & such online demonstrating the exact procedure.

The Headspace Comparator is for brass resizing & reloading. Chamber Headspace Gauges are used for setting Chamber headspace. A Go & No Go Gauge. However, many of us use just a Go Gauge, a then a piece of tape on the back of it to act as a No Go Gauge. I myself use stainless steel shims instead of the tape. I have a Go Gauge & use a .0025” shim behind it to set for No Go. Below is a common set of Go & No Go Gauges.

Good advice- and always good to know how to check headspace..... but the bolt sleeve would not change headspace. Even with a bolt sleeve that is a few thousands longer or shorter the headspace would still be set by the bolt head and action lugs.

Technically “yes”.. ​and there is controversy there; however, it should still be checked as aspects of the headspace with a longer or shorter bolt sleeve can be different. I check no matter what.
