I believe the answer to my question has been implied a lot but never addressed as far as I can find but I just started reloading and am currently using my 1xfired hornady brass to develope a load for my rifle, I plan to get some alpha or Lapua brass for the match season in the interest of consistency, my concern is if I develope a load in this brass will the load I come up with be good in different brass? I will also be changing from cci200lrp to cci450srpmost likely. I understand I will have to adjust powder charge to get back to my speed but all else being unequal will this bullet at this speed this distance from the lands remain my best load or should I stop waisting components until I get the brass I intend to use and develope the load as I intend to use it ?
