Heard this year around these parts about a lot of duds with one batch of #11. I don't remember the brand though since I don't hunt with #11 anymore. In all the years of ML hunting and shooting I only had it happen once and that was on the range after a mid shooting session cleaning. It was with a TC New Englander 54 using #11 caps and I didn't pop one off after cleaning before I reloaded. I must have had some solvent stuck in the nipple. Second cap and the shot went off. I don't hunt with that one anymore but like to shoot patch and ball out of it on the range.
