Barrel cutting question

A lot of bad info above. It works, not just speaking theoretical, I've done it. If it's what you really want and don't mind the look, do it.

Fluting is, at least in part, about aesthetics. I don't care for this look though it's probably more about what I am used to seeing.

Since he said the rifle was a Bergara, it's probably a bolt action. I agree that 22" is already short for the round he's shooting. Cutting off 4" would definitely reduce velocity and increase the blast/noise. Here is a video on this specific round:

For me, it's less about losing velocity and energy (the 7 PRC should have plenty at my realistic hunting ranges) and more about OAL of the gun. I'm planning to order a Nomad Ti or LTi (~6" vs ~8") in the next few months. I love the idea of maximum suppression but an 8" silencer on a 22" barrel feels like it could be too much. Maybe I'm overthinking that part?

At the end of the day, it does seem like the best and most likely scenario is I keep this 22" barrel and if I want a shorter one in the future, buy a new one that's already 18" or 20".

You're not over thinking that part. My open country big mag (30 Nosler) is 22" and I only use 6" mufflers. It's the longest barrel I own on a suppressed rig. I think 18-20 is about right. 16" is handy in a blind though.

Cutting the solid portion of the muzzle off will change how the muzzle expands as the bullet is nearing and passing the muzzle exit. In the rest of the barrel the raised ribs are supported on either side of the bullet and high pressure gas as the bullet moves down the barrel. It the support of the ribs is removed at the muzzle the ribs are no longer supported on one end and the barrel will expand unsealing the bullet and allowing more gas to outrun the bullet to the muzzle.

Please help me understand how threading the end of the barrel (muzzle exit) doesn't add to this idea of muzzle expansion? I.E. how does cutting into the fluted portion affect the stability of the muzzle end but turning it down to thread a muzzle device not affect it?

Genuinely have always been curious about this.
