I have loaded up a few different loads with them and have yet to find one that shoots well from my barrels...
My hunting load is a Hornady 180 SSP bullet, AA1680 powder and a SR primer.
I have shot many bullets, your Speer 180 works well too. as does my second choice the 180 XTP. Another one I like very much is the Speer 170 GDSP bullet.
