Keith, I did notice two of your loads are identical except for the primer. One 12g 2 1/2" load uses Fed 209 and one uses Cheddite. The difference between the two was an average of 10 FPS (?) and pressure of 100 PSI. That is not much of a difference. The reason I comment is some guys had higher pressures with Cheddites and some did not. Some recipes needed to drop an average of 2g of powder if using Cheddites to lower their pressures to levels consistent with the domestic primers. Since I don't load "hot" shells I don't really worry about the primer, but I see how some guys may need to have some testing done especially if they are loading something "snotty". Thanks for posting those recipes.
