l have a 2x EER Leupold on my SW Light Hunter. A 4x EER Lupold
on BAMBAM, My 460 SW PC. I have gotten a bit of powder residue on
the 460 and the Lite Hunter.. However, this is only AFTER an
extended range session or an IHMSA silhouette match..
My humble opinion. 2X EER Leupold is the best handgun scope made.. period
