Hi John,

Don't have much experience with the mags (yet)!!  Only have three and they are on the military tractors.  I have not had to do anything special with them (yet) only because they have all been recently rebuilt.

Never heard about putting them in th oven but it would make sense to dry them out a little and to put some heat to their moving parts!

I am sure Dennis or Joe or others can repond better than I!!
