Twist Rate vs Barrel Wear
- Thread starter MJT
- Start date
The answer has probably been verified one way or the other but the greater the centrifugal force the greater the radial pressure throughout the length of the bore would be. Measurable....maybe. Don't think the twist rate affects throat erosion from heat and quantity of powder burned.....my thoughts.
I take another view . Fast twists and heavier bullets combined with boat tails , do wear barrels faster . Is it measurable, maybe , but too many variables and I don't think it wears significantly faster .
Anytime you increase barrel time , i.e. Heavy bullets , slower powder faster twist , you've got to be increasing the time your barrel has to absorb the heat generated by the powder combustion.
Just my observations
I seriously doubt its enough that anyone would notice.
There is probably a bigger difference in cleaning regimen or powder choice.

Now you run into the evaluation of just when a barrel is "worn out".
Is it because it looks rough or worn down? Some worn things still shoot well for what they are. In the benchrest game a loss of accuracy can be noted and then the barrel is considered "worn out", even though it physically looks like new.
The evaluation is too subjective to answer definitively. Each of us has to evaluate the condition of a barrel. That evaluation can be as varied as we are.

Heat is what wears barrels out. Other factors get lost in the noise or are just negligible. JMHO.
