BSA,what's your load for the 250 gr Sierra? Thinking of using that bullet in my .338 Win mag.
Just Sierra book loads. I have tried from 67 to 70 grains of IMR 4350 with great success. I run R-P and w-w brass with CCI 250 primers. They shoot great and hit hard. Elk generally only take about 1 step and keel over... They also have some pretty good BC and SD numbers..
