I tried the .25 in my notoriously sticky MAG brand Sig mid-caps at our dusty field. Truth is most days I have to load up at home and hope I can do at least one re-load before the dust jams it all up. The armist bbs were used in first load up but alas they could not feed under them dry dusty conditions for the reload. Would I buy them? Yes. Would I grab something else? Yes. But that is why I put in an explanation, they do the job for most but not me and the specifics I need.
