Thread: Is RL17 a barrel burner?

For those unfamiliar with Quickload this what it offers. This load is close but needs a few tweeks. My muzzle pressure is below the safe limit set by icebug

And a comment of burning/erosion - it is not caused by pressure although obviously high pressure may have an associated high flame level. Erosion works best in the leed area where there is a transition from no rifling to rifling and the angle of the rifling (no matter what angle it has been reamed to) inevitably presents sharp edges, which are exposed to the super hot gases and unburned/still burning powder. Some powders are more aggressive to the rifling than others via abrasion as well. To a lesser extent the primer compound will also erode. At the muzzle the gases are less able to abrade/firecrack as they are travelling in the direction of the parallel rifling ie no exposed edges at an angle to gas flow. Any burning of the crown will occur from the jetting effect of the flame as the projectile exits but will never exhibit itself the same as leed erosion.
