I had a lousy experience trying to order 16 & 20 ga B&P shells in October. Seem to be out of stock on many items. Would love to try the shells, but was not happy with their stock situation.
I think the dust has settled a bit - you might want to try again. My understanding is that the issues they were dealing with were not of their own making.
Someone (who acted like he knew what he was talking about) told me today that Kent shells use nearly all the same components as B&P - anybody know if that it is true? Some of the Kent target loads are a bit cheaper than B&P's.
