I am running H4350 with the 168gr and H4831SC and some H4350 with the 208's. The H4831sc was shooting a touch better than the H4350.
My boss is going to lend me some Magnum primers to save me from having to buy some.....he is interested in the out come also. I am going to be setting up a 1000+ yard range out one some BLM out in the middle of no where and will test it out with the 168's on some steel hopefully this weekend.
