I've also had issues with a Defiant action in rough conditions. First PRS rifle was a GAP with a Defiance action. There was PRS matches where I had to clean the action out multiple times a day just to keep it running. Meanwhile, Surgeon actions around me where running perfectly fine with no cleaning required. Ended up galling the lugs on that action, as it was impossible to keep running with any grease on it at some matches.
I since replaced my Defiance on my PRS rifle with a Mausingfield, and it handles the fine dust much better. Worlds of difference. I'm not sure if I would everyone back to Defiance for a PRS rig. Runs great wet or dry, and the action is impervious to galling. A lot of better design features on the Mausingfield as well.
My ELR rifle has a Defiance Deviant, and I will admit that it is one of the smoothest actions I've ever handled. It has the raceways polished and the action is IonBonded. Slick as hell. Not sure how well it handles the grit as my ELR rifle is not exposed to adverse conditions for near as long as my PRS rifle.
I would take a Impact over a Defiance for extended shooting in really adverse conditions any day. But most of us aren't exposed to such ####ty conditions, and some rifles (like my ELR rifle) won't see such conditions so it really may not be a factor. The Defiance is a a great action, especially if spec'ed properly, but shooting for extended periods in real adverse conditions is not it's strong suit. There are other actions that are actually designed for that.
