This is what happens when the powder you are using too slow a powder for your rifle/component combination.

Step the speed of your powder up a notch. As an example, if you are using H4831, go to H4350, or from H4350 to H4895.

This should fix your problem.

You cannot over estimate the unimportance of nearly everything. John Maxwell
