The shells in Argentina were of fine quality. I went through 5250 rounds in 2013 without one misfire. They were Argentinian brands, all of them.

They burned clean and I had zero issues with gunk. My only issue with my 687 SP II Sporting was when I'd go through several hundred in a short time I would have to scrub plastic buildup out of the chambers, but a few strokes with a stainless tornado brush took care of that and restored perfect ejection in a minute or so. This was simply caused by shooting so fast that the barrels/breeches heated to the point that the plastic buildup occurred much quicker than normal.


May God bless America and those who defend her.
