Duskykiller,
I have not done any long range shooting with my .357 magnums so I am unable to offer any help there. I would recommend you call Robert Palermo at Penn Bullets and ask him directly. I spoke with him last October before I placed my first order because, quite frankly, I doubted the claimed 1600 fps with no leading. Bob spoke with me about hardness, obturation, powder burning rates, differing pressure curves and their effect on cast bullets, and so on. After the discussion I placed my order with Penn for 140 pounds of bullets (about 6,800).
A call to Bob would answer any questions you may have about his products..
