I will see how case life is, if its not to great i will back it down a couple of grains. I didnt get to chronograph this load because the sun was too low for the chronograph to work and we leave tomorrow for elk hunting so i wont have a chance to find another lighter load or chronograph this one until after the hunt.
I personally like it for being able to experiment new combinations with,.. I got tired of purchasing what I thought might work well just to find out they didn't or there was a better combination out there instead, It eliminates a lot of guessing and puts the proof in actuality for you.
I found out that the RL#17 powder works fantastic for the combination I wanted for my .338 WM for elk hunting,.. I tried it in the program 1st and then in the rifle with great results just like it deduced it would,.. great program!
