Bought some WWB .38 special range ammo at Walmart. Haven't bought factory .38 in 25-30 years. Didn't have time to load ammo, so I reluctantly bought some. The ammo, 130 hr FMJ, performed quite well. Very accurate from my M66 2-1/2". When I unloaded the cylinder, the brass seemed like it was about half the weight I was expecting. I haven't weighed any to compare to some of my vintage brass, but it sure seems lighter. Anyone else observe this phenomenon?
