Since you have experience with wildcats, perhaps you or others can offer some advice.
My 9.3x338 came in, and looks good. Now I want to develop some loads. I already worked with 250 gr bullets and IMR 4895, and that seems to be working out good.
Today, I discovered that RWS 9.3x64 brass holds 84.4 grs of water, and my 338 brass necked up to 9.3 holds 83.9 grs of water. Half a grain ain't much, so basically the capacity is the same.
In you opinion, does this mean that I can use published and reliable starting loads for the 9.3x64 in my wildcat?
