Carbon fiber wrapped barrels are NOT exactly known for their inherent accuracy,
Just to start with.
they are a compromise to achieve less weight
the compromise being accuracy in itself
---
Note: you do not see any, not even 1, carbon wrapped barrel on the firing lines at competitions
if they retained accuracy after being turned down then rewrapped, you might see one on the lines.
---
Aside from this, I have done a bit of research on carbon barrels because,
The idea is a good one, I want one, I would like to use one
however, I have not found any to be accurate enough
at least - Not CONSISTENTLY....accurate
Some may be decent, or produce accuracy at any given time but cannot be relied upon
---
From my research, and others testimonies who have tried and use them
(Mainly for a hunting rifle only, not for competition)
is that Proof is a 50/50 gamble
When they heat up they walk unpredictably
and each different brand of carbon barrel walks in a different manner
What I did find was that a Brand called BSF, seems to hold the best round type pattern once it heats up
as opposed to a larger scattered pattern which is what I see Proof produce.
---
I built one Carbon Chassis, Carbon barrel custom once and decided to try a
Bartlein Carbon wrap simply due to Bartleins cut rifling and their good reputation
Much less of a gamble with Bartlein should it not be accurate enough
---
The Bartlein produced phenomenal accuracy and held it for at least 10 shot strings
I did not go past 10 shots because it was not a Comp rifle so testing further to heat the barrel further to gauge walking would be insignificant in the realm of realistic use
I would guess patterns would open up as you put more rounds through
but this does not happen when hunting
I figured 10 shots, or even 5 shot groups would provide a realistic assessment of Bartleins carbon barrel
---
Bartleins also start off with a larger OD SS barrel to begin with
while others turn their barrel profile rather thin before wrapping
So you start off with a thicker barrel with a Bartlein to begin with which aids accuracy
My suggestion
Try a Bartlein or a BSF carbon wrapped barrel
---
Shown are the results of my testing in a barrel I chambered in .284 Win
the best / last group shown is a 6 shot groups, testing 3 different seating depths
more than adequate even for certain types of competition.
---
Lastly, you need to, have to, it is a requirement
---Load your own ammo to tailor it to the gun and the barrels individual characteristics
Specifically "Seating Depth"
if you are expecting ANY type of reliable accuracy
using Factory loads is a waste of time, money and your barrel life.
You cannot get around this, there are no cheat codes with using Factory Ammo
Even if you tried every brand of Factory ammo, the possibility of finding a winning combination of
"accurate factory ammo", you would be better off expecting to buy a winning lotto ticket.
How many tickets would you have to buy to increase your odds of winning?
There are not enough different combos of factory ammo available to find an accurate one
