[QUOTE="jbs2014, post: 1889677, member: 94052"] I had a shift in velocity and ES when I started firing the once fired brass in .408 and 338-378. I had to adjust the charges by about .5 grain on 338-378 and 1 grain on the .408 to get them back in the velocity node that I had found. If I remember 106 grains of Retumbo pushed my 275 grain RMBs to 3050 and with the once fired brass I had to step it p to 106.5 to get back into the 3050 FPS range. With the .408 I think I had 2856 with 133 grains of retumbo and I had to move it up to 134 grains to get to 2856. That is with setting the shoulders back .001-.0015. [/QUOTE]
