RE: 243 win.
Like Hawk says....bullets blowing up or being called failures is really a misnomer if the deer or whatever you are shooting at is dead. The only true "failure" I have had which means a hit deer and a non recovered deer remains the 165 BT from a 30-06 in the early more fragile version of that bullet. The 85 gr NPT's have piqued my curiosity for the 243. Cant wait to load some and see if they group...
