Mornin Boys, I'm testin my new sights out. I'm workin on my loads for the new setup. I shoot my own cast bullets which are 130 grain. I use Titegroup powder. The Hodgdon web site tells me that I should use between 3.5 to 3.9 grains. I have always found that usin the middle or low side will give me the best accuracy. (POI) I am now usin/testin 3.7 grains in my loads. (It may change.) I got to wonderin about the penetration of that amount. So I checked it out. This is what I found. I like my new log splitter..
