Federal 6.5 Backcountry?

[Andouille]

I think we will find that it will perform very much like a 6.5 PRC or 270 on bigger game like Elk. That will eliminate the "needs-more" issue.

Exactly, and maintaining reasonable effective range for shorter barrels used with suppressors.

Anyone saying that +Peak is not needed for 6.5 CM is also implying that any larger 6.5mm cartridge (6.5 PRC, 6.5 RPM, 6.5-300) is also irrelevant. Ironically, those criticizing +Peak probably also own larger "unnecessary" calibers. Last I checked, we're in a capitalist, free market economy where you can buy the V8 truck even if a V6 is available. Nobody is being forced to buy +Peak ammo, so why all the butthurt feelings?

Does anyone have any knowledge on if the higher pressure will affect wear on a suppressor out of short barrels (16")?

Likely has a muzzle pressure near that of 6.5 PRC with similar muzzle velocity. One could plug both into quickload or GRT and get a better idea of muzzle pressure, though 6.5PRC may have a longer impulse because of the higher powder capacity and slower burn speed.
