I was talking to Scott this morning and he said he saw Hodgdon has published some new data for reloading the 2 7/8" 10ga. Three 1 1/4 ounce loads are listed using IMR Blue, Longshot and Win 572 powders. Pressures are 6500 to 7400 psi, velocities 1200 to 1225. This is great news and I hope over time they expand the number of 2 7/8" 10ga loadings. It probably wouldn't hurt to send them an e-mail thanking them for the data and expressing a desire to see more recipes for the Short Ten in the future.
