Corrosive Primers

[Contenderizer]

You reloading pros may be able to help me with this question. I have some Lellier & Bellot (Czech Republic) factory loads in 303 British. The boxes say that the primers are 5.3 mm Boxer. What is the likelyhood these primers are corrosive? If they turn-out to be non-corrosive this will make my wife very happy ... as I won't have to put the gun in the dishwasher after shooting.
