Yeah I understand all that. I found some Remington 9 1/2 M so I picked up 2 100 count. I have a nice sample of things to try so far. 3 different primers, 3 different powders, 1 type of bullet so far. I also do have 100 grain Spitzers from Weatherby. If the 115s don't produce I am going to try and find something around 90 grains. I'm pretty excited to start.
