In the posts that I have read here at MM, there are 2 different types of o-rings mentioned for shimming the 209 primer pockets.
Buna-N, and Viton.
McMaster-Carr
Metric o-rings
6.5mm×4.5mm×1mm
O.D.×I.D.×Thickness
Buna-N
Black
#9262K611
Durometer 70A (medium)
-20°/+250° Fahrenheit
$4.91 Pkg/100
4.91 cents each
Viton Fluoroelastomer
Brown
#1185N26
Durometer 75A (medium)

Which ones do YOU USE?
WHY did you choose them?
How do they work?
How many shots do they last for?
Thanks for your input.
