I'm loading 2.8 gr of Trail boss with the NOE 32gr cast pb. I get 1557 fps AVG VEL using a magneto speed. The 2.8 gr load is grouping very well at 50 yards.
I am trying to work out a 100 yard cast load. So far the increases in Trail Boss in my loads are being very predictable. I am weighing each load (cheating with a charge master).
I am using a Franklin Arsenal .17 cal funnel which is an external design and allows a full .17 diameter flow area. Makes life easy.
