Dober, I will try it again, I think I have a few more 130 AB's to shoot. You seem to be leaning towards RL22 not being temperature sensitive. I just don't know, I had a good time developing a load for the cup and core 130 grain nosler seconds. Do you think if I shot them out of a 26 inch barrel over 60 grains of RL22 that they would go to pieces on a deers shoulder? Your right my next major reloading investment is a chronograph.
