Went to the range today with a full box of cast bullet loads. Most testing was done at 50 yards, since I had no idea of the impact of these loads with the 1896 sights. While 50 yards gave me indications of good loads, they don't always indicate stability out to 100 yards or beyond. (The principal issue I had was the performance of my 65-yr old eyes with the original sights intended for 18-25 yr old recruits.)
The best 50-yd load was 18 gr. 2400 under a .309/204 gr 311299. 1.5" center to center. I was a little squeamish about this level of 2400 so only made up 5 rounds. I need to try this at 100 yds.
The best 100 yd load was 17 gr. 2400 under the same 311299, with a group of 1.25". I was shooting with my glasses and a homemade diopter made of pierced electrician's tape. While it's good to be good, it's better to be lucky in this case. I got a group of 1.5" at 50 yd. with this load.
Lighter charges of 2400 from 15-16 gr did not stabilize that 311299 as well as the 17-18 gr loads. My bore mikes out at .301-.3075 so maybe a 312-314 diameter cast will give good results. One load with a Lee .310/185 over 17 gr. 2400 also grouped at 1.25".
