For years I have used XTP's as my plinking load, however I make sure if my hunting load is different I work it out first and keep my rifle tuned to it during the off season. Reason being life can get busy and nothing like trying to cram it in for opening day b/c you got tied up doing other things.

If developing a load I don't bothering bringing a plinker, instead concenrtating on the task at hand and running a couple through the paces. I ear mark potentialsand start widdling down the list on further range sessions to find the one (or ones).
