I've been shooting some of Ga Arms bullets in my Blackhawk. I've not experienced leading with the first ones I bought(2 boxes of 300), but this last batch has been leading the crap outa my barrel. Same loads,brass and all that. This is a light load that's not supposed to be over 850fps,according to the book. I don't own a Chronograph. They're shooting to the same point of aim as the first ones.
Do batches run softer sometimes? I haven't looked for a "made on date" or batch number on the box. But something is different about these.
