All of that stuff is more alike than it is different. We need a good .290 caliber cartridge. How about the .290 SSSOB for SuperSonicSonOfABitch.
What is your take on the new 7mm Backcountry?

That's like buying a hot rod then bitching that it eats tires or gets crap fuel mileage.
Most of the bitching about hot rod rifles comes from others telling you you don't need it. mtmuley

"Need" is subjective - and you and I both aren't ones to listen to people telling us we don't "need" something.
I don't "need" a '68 K20 on 35" tires, but by god I'm going to have one before I die! I will also burn through a set of tires every 10k miles because science.
Same way with rifles, I know if I pump 300 rounds a year through my RUM it'll be making a trip to see @p_ham every 4-5 years. Just goes with the territory.

I sold a 1971 GMC K20. Bad move. Still have the 1986. And yes, I need 35's. mtmuley

I thought I needed 35s until I got 35s. Then I realized I needed 37s. I think that's where I stop. For now.
"One of the key issues with the 7mm Backcountry is the potential for accelerated barrel wear. With chamber pressures approaching 80,000 psi, similar to the 277 Fury, this caliber may significantly shorten barrel life—especially for those who regularly shoot in high-volume settings like military operations or precision shooting competitions."
If you assume those who shoot suppressed with shorter barrels (the target market) are often the ones who fire more rounds, it definitely sounds like something that will be great for the replacement barrel market.

For years people have said that there is “no free lunch”.
Not sure why this would be any different.
How many rounds did everyone actually shoot out of their hunting rifles this year.
I shot more because of fiddle farting trying to find a more accurate load after adding a suppressor.
But even then, an 18 inch barrel for a suppressor hunting rifle sounds nice.

Just to play devil's advocate here, if someone doesn't fire very many rounds, is a suppressor really necessary? And if you add the features of the latest noise suppression technology that includes exceptional hearing capabilities, shooters can stay with an unmodified and more longstanding firearm that does what firearms do best. That is, achieve target velocities with longer barrel life.

I am not understanding that sentence? “ are you saying to add a suppressor to a standard rifle in a historic cartridge?

I figure there two people that are going to buy the 7mm BC. The guy that wants the performance of the cartridge but only shots three rounds a year. The other is the guy how’s going to figure out how to reload this thing and that guy doesn’t care what the round count is because they just spin another barrel on.
By the time the guy in the middle burns out the barrel there will be some other new wiz bang cartridge they’ll move on to.
Shoot a rifle with a longer barrel that lasts longer and achieves required velocities and use inexpensive hearing protection.

I don’t fit either of those buckets. 60 rounds through mine so far, velocities are starting to get pretty consistent now. There is definitely a difference in velocity from the first box to the second two. Recoil is odd, it’s sharp but light. Nothing like an 06 but also not like a 308. It’s somewhere in the middle. It’s actually really nice. I am running a brake which is likely the cause. Higher pressure through the brake makes the brake brakier

A suppressor is never really “necessary” for most folks. Nice? Absolutely.
It’s not just decibel reduction, it’s also recoil reduction that comes into play.
Depends on the suppressor, but I find the noise reduction to be equally valuable as the recoil reduction
Also I’m waiting for the 7.62 backcountry or the 7.032 backcountry
