We also do reverse muzzle tapers. Like a Anshutz type muzzle. So for example we do a #2B contour with a .600 muzzle normally but then put a reverse taper on the muzzle. Looks like a mini breech end of the barrel type look… So like from .600” to a 45 degree taper up to a .700 or .750” diameter for a couple of inches so you have some meat to thread the muzzle for a suppressor attachment etc…I have a 26" light palma steel, it's the same weight as a benchmark sendero carbon, shoots better too. If a person wants lighter weight, run a light palma, still able to cut 5/8x24 for a muzzle device.
Alot more meat around bore and chamber area, comparing 7prc to 223. Also a skinny barrel can have a taper left at muzzle threads to act as a shoulder. I've had several pencil barrel ar pipes that were .560 dia in front of gas block and then flared out to provide shoulder for muzzle threads.I did a 20” .223 barrel with the lightest contour that I could put 5/8”x24 muzzle threads on, it came out to 55 oz which was a pound heavier than my 20” 7 PRC barrel.
Apropo of nothing, here's a rando vid (re: cryo treatment) on how Krieger does their barrels.
Extreme cold shouldn't necessarily affect a well-done carbon fiber wrap based on aero and space applications.

THIS.Too many people wanting to be reimbursed for time and damages lost due to their own poor decisions.
No. They both contracted but at different rates.Metal contracted from being so cold and the carbon didn't?
Wrong. This is what happens when people who know nothing about materials play amateur metallurgist and pay for thermal processing without understanding what's going on.@LRTalley - if I was you, I would go and talk to the cryo company now. It was their service that ultimately ruined your barrel, while it was in their care. They need to take care of you. IMO, its their responsibility to make this right.
This depends in some part on the geometry of the bonded parts especially the metallic one and the stresses imposed on the CF.Extreme cold shouldn't necessarily affect a well-done carbon fiber wrap based on aero and space apapplications
Don't those tanks have metallic fittings for pipe or hose connections?Carbon fiber space parts, such as cryo fuel tanks are 100% carbon, not steel wrapped in carbon.

Is the CF wrap bonded to the barrel at the ends? If so the wrap will be subject to axial stresses as the barrel changes length as well as diameter during contraction.

Sound reasoning, though a smith can custom machine a larger diameter permanent "adapter" to allow for larger threads/shoulder and be perfectly concentric. Just another way to skin that cat, and less expensive than the cfw.The reason I choose carbon wrapped barrels for a hunting rifle is to have enough meat at the muzzle for threading. On a 338 with 3/4" threads, you are pretty much limited to truck axle barrels, and carbon saves you a couple pounds. If you don't care about threading for a can, stick with steel.
