Bobby.... when using any new leather "whatever" I like to start by giving it a thorough cleaning with saddle soap and usually a coat of mink oil "type" (the more silicone in it the better) dressing.
I like to use some stuff called Leather New as my saddle soap of choice. Seems to have a lot of glycerine in it that I think helps the leather.
Once I've gotten the tab or glove thoroughly cleaned and wet from the soap, I'll take it out and shoot with it... the longer the better.
I believe that the "excercising" of the moist leather helps the break in period and helps extend the life of the tab or glove.
