In the IMR reloading handbook they show 24grms, not a 7/8oz load. That's a International load, but only about 10 or 12 BB's less then 7/8 so basically it's the same. In the data sheet that came with the CB-4100 wads they list three different loads with 700X for 7/8oz in a Remington hull. The 16grs/1200 fps at 6600psi, 17/1250 at 6800, and 18.5/1300 at 8600psi - so I'm loading 18grs and it shot good at 0 degrees. I'm assuming I lost 1500 psi or something because powders are tested at 70 or 72 degrees [ can't remember ]. The others may work at hotter loads but I found one for the components I have so I'll leave it at that. In the summer or warmer temps I'll go back to my lighter loads.
