Thread: Tell me about carbon wrapped barrels

Local gunsmith did some testing here recently.

Measured stiffness with carbon and equivalent weight carbon barrels and found they are identical.

For example my 24” proof research is a sender contour but same weight as a number 2 profile steel barrel and is just as stiff. However, all my no2 profile barreled rifles suffer in accuracy as the shot strings go past 3-5 shots and this is not the case with the proof, it shoots the same poi regardless of heat.

The way I view carbon barrels is that 1 they look good, 2 they shoot well, better than an equivalent weight steel barrel and 3 they are light.

One thing to consider is the conditions under which the stiffness test was done. To be useful the test should be done at elevated temperatures. Most epoxies tend to loose strength rapidly as temperature rises, typically becoming quite soft at 50C. I don't know the properties of the epoxies used to wrap barrels.
