I am trying to find reloading data for Solo 1250. Particularly for 12 ga. 1 1/4 ounce loads. I have some old data from Accurate powders, but a check of their site shows 1250 has been discontinued. Appreciate any and all help.
Solo 1250 was not recommended for 1-1/4 oz. loads, at least in my Accurate guides which 2005 is the latest I have.
It shows 1-1/8 loads at 1250 FPS already at maximum pressures, so It's easy to see why they do not advise heavier loads. Pressures would exceed SAAMI maximums.
AA Solo-1250 simply is not a proper choice of powder for 1-1/4 oz, loads.
