Hello again,

I have a questions related to reloading:

Q) I plan to reload my test rounds using previously fired brass (full-length resized). Then, once I find the right load, I want to load new brass (which can be from a different manufacturer). Is there a problem with this method? Can a good accurate load developed using re-used brass turn out not good when loaded in a new brass?

Here is a test round (empty) I made for 300 WM using new Nosler brass. This was to test C.O.L. I figured I can seat the bullet a bit longer than standard in my Sauer 202 (C.O.L. = 3.38 inches). The planned test charge is 72 grain to 76 grains of Norma MRP.
