Well the Unique load didn't fare well with the 158 SWC at 6.0 gr, wondering if it needs a bigger charge of it. 5.5 gr of W-231 didn't do well either. The bullets measure .358 and are pretty close in weight, maybe a tenth or 2 gr variance. It seems like the 158's want to be driven harder, 13.0 gr #2400 under the JHP was nicer to shoot and grouped fairly well, going to try the KT-SWC at that charge and see how it goes.
