Revolvers are cool but is there anyone who makes a stout bolt-action long gun out of exotic heavy alloys that boast improved durability?

Chunky pieces feel good and it would make for a nice heirloom gun.

8620 is not some exotic alloy. Anyway, there's no need to look for an alloy with improved durability, bolt actions last practically forever as it is. Look at Mosin Nagants, plenty of them are over a century old and still work fine.

It's not the practicality of it, more like a nice feeling. The bore would probably last longer if you shoot a barrel burner cartridge too.

The bolt action design has proven to be both durable and accurate.

Benelli makes some heirloom tier shotguns in my opinion. They now make rifles.

There are bolt actions that exceed $5,000 in larger calibers built for accuracy and durability, look at Accuracy International. There's a pretty incredible amount of higher end and collectible modern firearms but they tend to start about 5x higher than what most people commonly use.

Basically this, and modern technology gives us even better quality (lined barrels, coated parts, higher quality metals) as well as better ability to store and preserve our valuables. Any current bolt action will function beyond your lifetime with reasonable care and cleaning.

Mosin-Nagant, being among the first bolt actions are still working well almost 100 years later. AKs have been used and abused for decades without failing.

I've read a few articles about various steels being used for barrels to see what lasts longer, and very few alloys exhibit any actual improvement. Tool steels, high impact steels, high temperature steels, they all seem to experience wear at about the same rate, except for high cobalt alloy steels. The problem with those is that they're hard to machine, so a barrel that lasts twice as long isn't great if it costs five times as much. Just buy five barrels regular barrels... Or do what sensible people do, use good coatings on a good barrel. They last longer and don't cost much.

I for one, have simply purchased a Winchester Model 70 Extreme Weather Stainless, comes out of the box with a quality buttstock that's got a strong aluminum frame, factory bedding, massive extractor and sturdy blade ejector, and everything is stainless steel. In .308 Winchester, it feeds smooth and fires accurately, along with how it will outlast me even if it's used in harsh weather and not terribly well maintained. The barrel will last a long time, and replacing it won't be expensive or difficult.

They use stellite sleeves in machineguns, having one in a rifle would probably be interesting. Would a tungsten alloy sleeve work? In general making a barrel as laminate of different materials seems like a viable idea.

Oh and speaking of tungsted, apparently they use it for outsidecoating https://www.winchesterguns.com/products/rifles/model-70/current/model-70-extreme-tungsten.html

I'm pretty sure that's just the name of a cerakote color, it's not actual tungsten. Also I think the reason stellite is used in MG barrels is mainly for wear resistance at high temperatures, I don't think it would provide much benefit in a bolt action.

Stellite is supposed to slow down throat erosion drastically. You might also have a rifle in .220 swift or .22-250 that are quite hot.

Speaking of cobalt, check this suppressor out.

  What about this as a bore liner?
